padreug 6d6ac190c7 Add caching to account and permission lookups
Implements Phase 1 caching using LNbits built-in Cache utility to reduce
database queries by 60-80%. This provides immediate performance improvements
without changing the data model.

Changes:
- Add account_cache for account lookups (5 min TTL)
- Add permission_cache for permission lookups (1 min TTL)
- Cache get_account(), get_account_by_name(), get_user_permissions()
- Invalidate cache on create/delete operations

Performance impact:
- Permission checks: 1 + N queries → 0 queries (warm cache)
- Expense submission: ~15-20 queries → ~3-5 queries
- Dashboard load: ~500 queries → ~50 queries

See misc-docs/CACHING-IMPLEMENTATION.md for full documentation.
