Align frontend with updated OpenAPI schema and PATCH operation (#13)

## Summary

Align frontend with updated OpenAPI schema (rename `format` → `bank`, add `pipeline`) and introduce a dedicated `PATCH` operation for partial updates in react-openapi.

## Changes

### react-openapi: new `patch` operation support
- Add `patch` to `ResourceConfig.operations` type
- Separate PUT/PATCH detection in resource-config transformer
- `update()` now always calls PUT; new `patch()` method returned conditionally when spec defines PATCH
- Admin form still uses PUT for full replacements

### Fetch Request custom pages: schema alignment
- Rename `format` → `bank` in create form fields and TypeScript models (`FileSource`, `EmailSource`)
- Add `pipeline` field to create form and `FetchRequestCreate` model
- Export `PipelineType` from barrel index

### Fetch Request retry: use PATCH
- Retry handler now calls `patch(id, { status: "pending" })` instead of the generic `update()`
- Removes `useMutation` wrapper; uses simple local `retrying` state for loading

### Fix Account display in detail page
- Resolve FK displayFormat target in detail field rendering (was always using fetch-request format)
- Fix page title to use `applyDisplayFormat` with resolved FK objects instead of non-existent `account_name`
- Move `useMemo` before early returns to fix hooks ordering violation crash

## Testing
- Custom fetch request create form includes `bank` (select) and `pipeline` (select) fields
- Retry sends `PATCH` instead of `PUT` — no more 500 errors
- Detail page shows proper account name instead of `—`
