Averion Redeem

**Bugfixes**

- `minAccountAgeHours` now checks the real first server join time (PlayerConnectEvent), not when the player first opened the referral tab

**New Features**

- **Referral Milestones**: Commands that run when a referrer reaches a specific number of referrals — configurable in the admin panel under Referral → Milestones

- **Copy Code**: Referral code is now a clickable text field (CTRL+A + CTRL+C to copy)

- **New Players Only**: New "Max. hours since 1st join" field — blocks players who have been on the server too long (0 = disabled)

- **Translation System**: All UI texts moved to `lang/de.json` and `lang/en.json` — add your own language as `lang/xx.json` in the mod folder (template: `lang/example.json`)

- **Referral Log Player Filter**: Search field in the log — filter entries by player name (redeemer or referrer)

**UI Improvements**

- StatusLabel now shows errors in red and success in green (was always green before)

- Redeem button is now highlighted (primary style)

- History tab is now labeled "Verlauf" in German

- History rows have a gold accent strip on the left

- Exhausted codes in the admin panel are highlighted in red

- Toast notification on successful code redeem

- Double-clicking the redeem button is prevented (`locksInterface`)

- Referral config labels simplified and clarified
