OmniPanel v18.5.304 - Lag Control, Repair, Player Actions and Region Flags

REAL FIXES
- Replaced the overlapping AntiLag configuration route with one exact-title Lag Control GUI.
- Disabled the duplicate legacy AntiLag cleanup scheduler; Core159Support is the single cleanup runtime.
- Added advanced Lag Control settings for item, XP-orb and projectile age, safety limits, named/lored item protection, world filtering, protected materials, scans and manual cleanup.
- Removed the old non-operational Removed Board / DisabledStat command route from OmniPanel startup registration.
- Reworked Repair Equipment to repair and write back every damageable inventory slot, armor slot and offhand item. Mending is not required.
- Moved the existing advanced Player Actions pages into the real Player Actions route instead of opening a competing mini-menu.
- Added region-flag aliases for safe fall/no-fall-damage (including legacy null4 naming), safe fire, safe void, no flight, no elytra, no pearls, no fireworks, no projectiles, command lock and other current flags.
- Safe-fall now resets fall distance after cancelling damage; safe-fire clears fire ticks.
- Restyled the Command Center utility controls with a consistent blue theme.

REMOVED DUPLICATE/DEAD LOGIC
- Duplicate legacy AntiLag scheduler.
- Legacy AntiLag GUI entry route.
- Removed Board command registration.
- Separate More Player Actions overlay route.

DATA SAFETY
- No saved player, kit, punishment, event, region or configuration data is deleted.
- Existing protected-material lists and region flag files are preserved.
