The owner mutes a repository once, and its asks leave the inbox and the phone but not its own page #1597

Split from #1112 (a person's ask).

Done:

• [ ] A mute per repository, saved per user (a named migration), set from a chip on the home's needs-you.
• [ ] Applied to /live/on-you, the home and /api/v1/asks; a muted repository sends no push to the phone.
• [ ] Its asks still exist and still count on the repository's own page.
• [ ] Tests: a muted repository's pull is not in /live/on-you; unmuting brings it back; its page still counts it.

Before pushing, run bun test test/asks.test.ts test/asks-expiry.test.ts test/check-list.test.ts with your own tests: earlier tries at this work went red on exactly those home and asks tests. A test that goes red in this pull is fixed in this pull. Name any new test file in GATE in scripts/gate.ts.

Parked by the crew: the check failed ("report mode is loud to admins, and to nobody else > reported: the Capacity page says it once, as a note; vitals do not") and the decider saw no point in another try (pull #1651 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.
