feat(newznab): support multiple named indexers (#1271)

## Summary

- add a named Newznab indexer table with per-indexer URL and API key
settings
- search every configured indexer and retain the originating indexer
name on each result
- namespace cached release IDs across connections and isolate individual
indexer failures
- preserve the legacy single-indexer settings as a fallback
- support masked API-key cells and trusted SABnzbd prefetching for named
indexers

## Validation

- 121 Newznab and SABnzbd backend tests passed on Python 3.14
- Ruff passed for all changed Python files
- frontend TypeScript and strict lint checks passed
- all 134 frontend unit tests passed
- frontend formatting check passed

## Compatibility

Existing `NEWZNAB_URL` and `NEWZNAB_API_KEY` configurations continue to
work whenever `NEWZNAB_INDEXERS` is empty.
