[Due for payment 2026-05-18] ReportActionCompose 7: Footer self-subscribe + file deletions + offline guards

[cristipaval]

ComposerFooter becomes self-contained: reads exceededMaxLength from context, renders OfflineIndicator, TypingIndicator, and ExceededCommentLength itself. ComposerLocalTime gets an offline early-return. ComposerDropZone passes isOffline to useShouldAddOrReplaceReceipt. Deletes ComposerExceededLength.tsx, ComposerImportedState.tsx, and ReportActionComposePlaceholder.tsx.
