Fix i18n gaps in Mail integration; correct stale beta-bug messaging

Localize mailAccessNote and AppleMailService's account-count string
(was a manual singular/plural literal, now uses inflect syntax). Also
correct the requestAccess() doc comment and the suspectedPlatformBug
fallback message, both of which still asserted "known macOS 27 beta
issue" — that diagnosis was wrong (see 6b4448d): the real cause was a
missing entitlement, already fixed. The instant-failure heuristic stays
as a defensive fallback, just no longer misattributed.
