feat(tui): add usage report command [4 of 4]

[fcoury-oai]

Why

Users need a local way to inspect which Codex features are consuming tokens over the current day or week.

What Changed

• Adds /usage, /usage week, and /usage weekly.
• Renders a status-like usage card with token-share sections, half-height bars, daily hints, and weekly period text.
• Adds TUI snapshot coverage for normal, weekly, and unattributed usage states.

How to Test

1. Start Codex from this branch.
2. Run /usage and confirm the daily usage card appears.
3. Run /usage week and confirm the weekly title/period appears.
4. Confirm empty or unattributed usage produces the expected message instead of a blank card.

Targeted tests:

• cargo test -p codex-tui usage_output

Stack

1. #24121 - Usage storage

3. #24123 - App-server usage API
4. #24124 - TUI /usage command (this PR)

Wrap usage error text before drawing card

When /usage fails with a long app-server error (for example a backend/SQLite error string), this creates one unwrapped line and only clamps the requested inner width afterward. with_border_with_inner_width still expands to the widest provided line, so the error card can exceed the terminal width instead of wrapping like the normal usage messages; wrap the failure message before passing it to the bordered card.
