Subject: [PATCH] fix: eliminate guaranteed 404s (ru menaion-bundle, unmapped
 commemorations)

- loadMenaionBundle: ru resolves to cu bundle (no RU liturgical texts by design)
- autoPreload: fetch cu bundle once; keep ru+cu lives for current month
- calendar view: fetch shared commemorations only for mapped feast CIds
