This flag fetch all keysets from the db into the wallet, which is wrong given that we're initiating it for a mint. And load_mint sets the first keyset from all the keysets from the db, irrespective of the unit and the mint.
Fixes#175
## Routstr v0.1.3 — 2025-09-15
### Highlights
- **DB-backed settings with live updates**: Env vars seed on first run; DB is the source of truth (except `DATABASE_URL`). Manage via Admin UI or `PATCH /admin/api/settings`.
- **Models moved to database** with background sats-pricing computation and optional periodic refresh.
- **Smarter max-cost reservation**: Discount based on prompt tokens and `max_tokens` using `TOLERANCE_PERCENTAGE`, with a `MIN_REQUEST_MSAT` floor.
- **Faster startup and provider discovery**; `.onion` endpoints use Tor proxy by default.
### Breaking changes
- **Configuration is DB-first** after bootstrap. Env changes won’t auto-apply (besides `DATABASE_URL`).
- **Models endpoint**: Use `/v1/models` for canonical model info; `/v1/info` keeps an empty `models` field for back-compat.
- **Legacy pricing envs** are auto-mapped but deprecated:
- `MODEL_BASED_PRICING` → `!FIXED_PRICING`
- `COST_PER_REQUEST` → `FIXED_COST_PER_REQUEST`
- `COST_PER_1K_*` → `FIXED_PER_1K_*`
### Added
- **SettingsService** with env→computed→DB merge; runtime edits; app metadata (name/description) applied to OpenAPI.
- **Automatic migrations** on startup; new tables: `settings`, `models`.
- **Per-model sats pricing** and per-request maximums computed in the background.
- **Pricing controls**: `FIXED_PRICING`, `FIXED_COST_PER_REQUEST`, optional per-1k token overrides, `MIN_REQUEST_MSAT`.
- **Azure chat support**: Optional `CHAT_COMPLETIONS_API_VERSION` adds `api-version` to `/chat/completions`.
- **Derive `NPUB` from `NSEC`** during bootstrap if not provided.
### Changed / Improvements
- **Proxy header hardening**: Strip sensitive headers; replace Authorization with upstream key when configured.
- **Discovery**: Read `RELAYS` from settings; Tor proxy defaults for `.onion` via `TOR_PROXY_URL`; faster announcement fetching.
- **Admin**: Improved auth/log UX; fixed log search; show mint balances in dashboard.
- **Performance**: Optimized startup; lazy DB info loading.
### Fixed
- **Refunds**: Correct msat→sat conversion; configurable refund cache TTL via `REFUND_CACHE_TTL_SECONDS`; better error mapping for mint outages.
- **Balances**: Reserved balance reporting and negative-reserved edge cases.
- **Tests**: Updated to patch settings and use fixed-pricing flags.
### Upgrade notes (from v0.1.2)
1. Ensure `DATABASE_URL`, `UPSTREAM_BASE_URL`, and `ADMIN_PASSWORD` are set. Optionally set `UPSTREAM_API_KEY`, `RELAYS`, `CASHU_MINTS`, `TOR_PROXY_URL`.
2. Start the service; automatic Alembic migrations will run (`settings`, `models` tables).
3. Configure settings via Admin UI (`/admin`) or `PATCH /admin/api/settings`. Env changes after first run won’t apply automatically.
4. Prefer new pricing envs or a `models.json` at `MODELS_PATH`. Legacy envs are mapped but will be removed in a future release.
5. Optional tuning: `TOLERANCE_PERCENTAGE`, `MIN_REQUEST_MSAT`, `PRICING_REFRESH_INTERVAL_SECONDS`, `MODELS_REFRESH_INTERVAL_SECONDS`, `ENABLE_*_REFRESH`.
6. For Azure, set `CHAT_COMPLETIONS_API_VERSION`.
