refactor(modpackchecker): Batch 2 fixes - centralized service, rate limiting, schema fixes

Browse Source 
NEW: app/Services/ModpackApiService.php
- Centralized API logic for all 4 platforms
- Technic build number cached for 12 hours (RV-Ready)
- Single source of truth for API calls

Controller (ModpackAPIController.php):
- Now uses injected ModpackApiService instead of duplicated code
- Added RateLimiter: 2 requests/minute per server on manualCheck()
- Returns 429 with countdown when rate limited
- Removed 400+ lines of duplicated API code

Console Command (CheckModpackUpdates.php):
- FIXED: updateDatabase() now uses server_uuid (not server_id)
- FIXED: status column uses strings ('update_available', 'up_to_date', 'error')
- FIXED: Technic API now uses dynamic build via service
- Now uses injected ModpackApiService

SECURITY:
- Rate limiting prevents API key abuse via button spam
- Technic build caching reduces external API calls

*
* HOW IT WORKS:
* 1. Finds all servers with MODPACK_PLATFORM egg variable set
* 2. Loops through each server, checking the appropriate API
* 2. Loops through each server, checking via ModpackApiService
* 3. Stores results in modpackchecker_servers database table
* 4. Dashboard badges read from this table (never calling APIs directly)
*
* RATE LIMITING:
* Each API call is followed by a 2-second sleep to avoid rate limits.
* For 50 servers, a full check takes ~2 minutes. Adjust sleep() if needed.
*
* PLATFORM SUPPORT:
* - CurseForge: Requires API key in settings (configured via admin panel)
* - Modrinth: Public API, no key needed (uses User-Agent)
* - FTB: Public API via modpacks.ch
* - Technic: Public API, uses slug instead of numeric ID
*
* DATABASE TABLE: modpackchecker_servers
* This table caches the latest check results. See migration file for schema.
* Uses updateOrInsert for upsert behavior - first run creates, subsequent update.
*
* EXAMPLE OUTPUT:
* Starting modpack update check...
* Found 12 servers with modpack configuration
* Checking: ATM9 Server (a1b2c3d4-...)
* 🟠 UPDATE AVAILABLE: All The Mods 9 - 0.2.60
* Checking: Creative Server (e5f6g7h8-...)
* Skipping - missing platform or modpack ID
* Checking: Vanilla Server (i9j0k1l2-...)
* 🟢 Up to date: Adrenaserver - 1.7.0
* Modpack update check complete!
*
* ERROR HANDLING:
* If an API call fails, the error is logged to the database and the command
* continues to the next server. One failure doesn't stop the whole batch.
*
* DEPENDENCIES:
* - Database table: modpackchecker_servers (from migration)
* - Settings: modpackchecker::curseforge_api_key (for CurseForge only)
* For 50 servers, a full check takes ~2 minutes.

* 1. MANUAL CHECK (manualCheck method)
* - Called from: Server console "Check for Updates" button
* - Behavior: Makes LIVE API calls to modpack platforms
* - Use case: User wants current info for a specific server
* - Rate limit consideration: One server at a time, user-initiated
* - Behavior: Makes LIVE API calls via ModpackApiService
* - Rate limited: 2 requests per minute per server
*
* 2. DASHBOARD STATUS (getStatus method)
* - Called from: Dashboard badge component (UpdateBadge.tsx)
* - Behavior: Reads from LOCAL DATABASE CACHE only - NO external API calls
* - Use case: Show update indicators for all servers on dashboard
* - Why cached? Dashboard loads could mean 10+ servers × multiple users =
* rate limit hell. Cron job populates cache instead.
*
* CRITICAL DESIGN DECISION (Gemini-approved):
* The dashboard badge MUST be "dumb" - it only reads cached data. If we let
* the dashboard trigger live API calls, we'd hit rate limits within minutes
* on any panel with more than a handful of servers. The CheckModpackUpdates
* cron command handles the external API calls on a schedule with rate limiting.
*
* PLATFORM SUPPORT:
* - CurseForge: Requires API key (configured in admin panel)
* - Modrinth: No key required, uses User-Agent identification
* - FTB (Feed The Beast): Public API via modpacks.ch
* - Technic: Public API, uses slug instead of numeric ID
*
* DEPENDENCIES:
* - Blueprint Framework (BlueprintAdminLibrary for settings storage)
* - Pterodactyl's DaemonFileRepository (for file-based modpack detection)
* - Database table: modpackchecker_servers (created by migration)

* Get cached update status for all of a user's servers.
*
* THIS IS THE DASHBOARD BADGE ENDPOINT.
*
* CRITICAL: This method ONLY reads from the local database cache.
* It NEVER makes external API calls. This is by design.
* It NEVER makes external API calls.
*
* WHY CACHED-ONLY?
* Imagine a panel with 50 servers across 20 users. If each dashboard
* load triggered 50 live API calls, you'd hit rate limits in minutes.
* Instead, the CheckModpackUpdates cron job runs hourly/daily and
* populates the modpackchecker_servers table. This endpoint just
* reads that cache.
*
* The React component (UpdateBadge.tsx) calls this ONCE on page load
* and caches the result client-side to avoid even repeated DB queries.
*
* RESPONSE FORMAT:
* Keyed by server UUID for easy lookup in the React component.
* Only includes servers that have been checked by the cron job.
*
* @param Request $request The incoming HTTP request (includes auth user)
* @return JsonResponse Keyed by server_uuid, contains update status
*
* @example Response:
* {
* "a1b2c3d4-...": {
* "update_available": true,
* "modpack_name": "All The Mods 9",
* "current_version": "0.2.51",
* "latest_version": "0.2.60"
* },
* "e5f6g7h8-...": {
* "update_available": false,
* "modpack_name": "Adrenaserver",
* "current_version": "1.7.0",
* "latest_version": "1.7.0"
* }
* }
*
* @see CheckModpackUpdates.php (cron command that populates this cache)
* @see UpdateBadge.tsx (React component that consumes this endpoint)
* @param Request $request The incoming HTTP request
* @return JsonResponse Keyed by server_uuid

/**
* =============================================================================
* MODPACK VERSION CHECKER - API SERVICE
* =============================================================================
*
* Centralized service for all modpack platform API interactions.
* Used by both the Controller (manual checks) and Command (cron checks).
*
* SUPPORTED PLATFORMS:
* - Modrinth: Public API with User-Agent requirement
* - CurseForge: Requires API key (configured in admin panel)
* - FTB: Public API via modpacks.ch
* - Technic: Public API with dynamic build number caching
*
* WHY A SERVICE?
* DRY principle - both the manual check button and the cron job need
* the same API logic. Centralizing it here means:
* - One place to fix bugs
* - One place to add new platforms
* - Consistent error handling
* - Shared caching (e.g., Technic build number)
*
* @package Pterodactyl\BlueprintFramework\Extensions\modpackchecker
* @author Firefrost Gaming / Frostystyle <dev@firefrostgaming.com>
* @version 1.0.0
