feat: MAM room to ratio, Queued page size and ETAs, MyAnonamouse settings tab

[mikaeltarquin]

Summary

• MAM panel: Buffer → Room to ratio. Shows how much more can be downloaded (not freeleech) before the ratio drops below Keep Ratio At Least (1.0 when that's off), after Shelfmark's active MAM downloads. The plain buffer is in the tooltip. /api/mam/account and /api/mam/ratio now return keep_ratio and room_bytes.
• Queued page summary. Tiles at the top: total size and item count (Up next + saved picks), what counts against the ratio, room to the ratio, upload credit for the whole queue (BP cost and, for admins, the wait at the estimated BP/hr), and when the last item can start.
• Queued page ETA per saved item. When the item can start once both the ratio and an unsatisfied slot allow:
  • Ratio: picks that fit go first (mirroring the auto-get check, including the small-ebook exception); the rest are priced cumulatively in queue order as upload credit (50 GB steps, 500 BP/GB) and the time to earn the missing BP.
  • Slots: MAM picks take the slots free now (after Up next and the kept-free slots), then each as a seeding torrent reaches 72 h, then the queue's own 72 h after they start. MAM's download pause holds everything. Without the client's seeding times, picks past the free slots show "For a slot, time unknown". /api/mam/unsat-timing now returns free_seconds for every seeding torrent; /api/mam/ratio returns unsat_check.
• MyAnonamouse settings tab under Settings › Indexers, after Prowlarr. A frontend split of the prowlarr_config backend tab (via SPLIT_TABS), so values save to the same file and no migration is needed; the first part keeps the prowlarr_config id so old links still work. A notice shows on the tab when Prowlarr is off. Text pointing to "Prowlarr settings" for MAM updated, env-var docs regenerated.

Testing

• Frontend: typecheck, oxlint (--deny warnings), oxfmt, vitest (371 passed), with new tests for the estimator (ratio, cumulative credit, slots, pause, unknown timing), formatWait and the settings split.
• Backend: ruff, basedpyright on changed modules, tests/prowlarr (812 passed) with new tests for room-to-ratio and free_seconds. Full suite has the same 11 environment-related failures as main.
• Not checked visually in a running app.
