/asked follow-ups: the oldest unmet asks must never fall off, and a phone shows the crew's last activity #709

Pillar: P0 Trust alignment (follows #611, merged as pull #674). One run.

• [ ] The default view is "nothing merged yet, oldest first", but the scan reads the newest 2,000 asks and then sorts, so on a large repository exactly the oldest unmet asks are dropped. Make the scan follow order, or filter and sort in SQL. Test with more asks than the limit.
• [ ] At 390 px the meta line truncates, so the pull and "crew …" text never shows on a phone. Wrap the meta, or put the crew's last activity first. Look at phone width in the pull.
• [ ] Remove the leftover "newest first" wording in the askedIn doc comment and the test file header.
• [ ] A test for agent-comment activity (only runs are covered today).
