Knobs: the autonomy card shows the week's budget as a share of the week and a pace, with no daily dollar ceiling #10623

The other box left on #10461.

Done:

• [ ] autonomyCeilingUsd is gone from the autonomy card (src/web/studio/crew.ts, src/web/studio/decisions.ts, src/web/pages/settings.ts) and the TUI autonomy screen (src/tui/screens/autonomy.ts); they show the week's budget as a share of the week spent and the pace it is spending at.
• [ ] src/crew/autonomy.ts, src/crew/dispatch.ts and src/crew/ceiling_stagger.ts gate on the week's budget, not a daily ceiling; the column in src/core/repos.ts is dropped by a migration or left unread, said in the pull.
• [ ] A test that dispatch holds when the week's share is spent and the pace is ahead, and one that the card renders no dollar ceiling field.
• [ ] bun scripts/design-lint.ts and the full bun test pass before the push.
