feat: implement /recover command for listing and recovering soft-deleted bounties

- Add recover_bounty method to BountyService (admin-only)
- Add cmd_recover handler for listing and recovering deleted bounties
- Register /recover command in bot.py
- Add /recover to bot command list

/recover - list all recoverable bounties (sorted by deleted_at desc)
/recover <id...> - recover specific bounty(ies)

Output formats:
List: [#1] Deleted bounty | 🗑️ Deleted 2 Apr 2026
Recover: ✅ Recovered bounty #1. or ⛔ Bounty #5 not found or not deleted.

Fixes #49
