Add Allowance v1.2.1

[BenGWeeks]

Add Allowance v1.2.1 for vetting. Allowance schedules individual recurring payments from an LNbits wallet to a Lightning address or LNURL-pay endpoint, in sats or fiat. Its focus is wallet-based allowance management, anchored schedules and clear per-payment history.

The extension uses LNbits payment services, wallet authorization and existing dependencies. Automatic retries are bounded; pending or uncertain payments retain their identity. Eligible failed or skipped occurrences can be paid explicitly after confirmation, preserving the regular schedule. Recipient requests enforce public HTTPS, with exact operator-owned exceptions for split DNS. This is a native Python extension, not a WASM component.

Validation:

• python3 check.py allowance passes, including archive hash, required files, config compatibility and icon.
• The submitted tagged source archive contains exactly the same file bytes as the published installation ZIP; native fresh installation and reinstallation passed on LNbits 1.6.1 with FakeWallet and no external network.
• Release CI passed SQLite regressions, PostgreSQL and native installation/upgrade checks on LNbits 1.6.0, 1.6.1 and 1.6.2. Testing scope and operator guidance are documented in the repository.
• Browser checks cover inactive allowance creation/edit/delete, payment-history actions and mobile FAQ layout. Payment fixtures use synthetic data and intercepted APIs; settlement tests use FakeWallet.

Screenshots show the released UI with synthetic allowance data, not live recipients or funds.
