Add daily traffic limits, auto-sort packages, Debrid-Link multi-key improvements

Daily traffic limits:
- Per-provider daily download limit (configurable in GB per provider)
- Per Debrid-Link API key daily limit (individual limits per key)
- Usage tracking with automatic daily reset at midnight
- Provider is skipped when daily limit reached, falls back to next provider
- Reset button per provider and per Debrid-Link key in account settings
- Hoster routing skips daily-limited providers gracefully

Debrid-Link multi-key improvements:
- Keys now display with labels (#1, #2...) and masked tokens in account list
- Option to show detailed per-key view with individual usage stats
- Keys that hit their daily limit are automatically skipped
- providerAccountId/providerAccountLabel stored per download item

Auto-sort packages by progress:
- Active packages automatically sorted to top during downloads
- Sorted by completion ratio, then downloaded bytes
- Toggle in settings (autoSortPackagesByProgress)

UI polish:
- Package column headers: flatter, more transparent design
- LinkSnappy mode label: "Login" renamed to "Web"
- Account list: new toggle for detailed Debrid-Link key display
- Account usage stats section with warning styling
