Logan Johnson 4ef23609b7 feat(mobile): show contextual names in channel conversations (#7895)
🤖
## Summary

In a channel conversation, two identities with the same display name
looked identical. In the example below, the channel shows "Bad Janet"
twice, for two different identities. A reader cannot tell which one was
added and then removed.

This PR uses the contextual names from the previous PR everywhere a
conversation names someone:

- Message authors, threads, forum posts and replies
- Reactions, the typing indicator, and system rows (joined, added,
removed)
- Inline mentions and the agent activity sheet
- The profile sheet title, which now matches the row that opened it

Names are compared against the channel's members, so a label only gets
longer when a real collision exists in that channel.

The mention picker labels each choice against every candidate, so two
"Honey" choices look different. When you pick one, it still inserts the
identity's own name ("@Honey"), so the message text does not change.

Part 2 of 3: #7894 (resolver) → #7895 (conversations) → #7896 (lists,
Search, Pulse).

### Related issue

Related to #2910.

### Testing

- A widget test checks that the profile sheet names an author the same
way the channel does.
- A unit test checks that two same-name mention choices get different
labels but insert the same wire name.
- `flutter analyze` is clean, and the full `flutter test` suite passes.
- Checked on an Android emulator against the live relay, in an archived
channel with two identities named "Bad Janet".
