fix(a11y): add missing aria-labels to message buttons

- FallbackContent: '(edited)' button now has aria-label='View edit history'
- Reply: ThreadIndicator as=button gets aria-label='View thread'
- Reply: ReplyLayout as=button gets aria-label='Jump to original message'

Addresses WCAG 2.1 SC 4.1.2 (Name, Role, Value) for icon-only buttons
and polymorphic div-as-button patterns in the message timeline.
