What and why

When the frame is too short for all eleven /statusline items, the list shows what fits and scrolls with the cursor, but nothing says more items are below. At 40×12, before:

 │ Choose what the footer shows:      │
 │                                    │
 │  ▸ [✓] Mode  (plan · work ·…)      │
 │    [✓] Model  (the model id…)      │
 │    [✓] Context window %  (tokens…) │
 │    [✓] Session cost  (running…)    │
 │  Space toggle   a all   n none     │

After:

 │ Choose what the footer shows:      │
 │                                    │
 │  ▸ [✓] Mode  (plan · work ·…)    █ │
 │    [✓] Model  (the model id…)    █ │
 │    [✓] Context window %  (token…)│ │
 │    [✓] Session cost  (running…)  │ │
 │  Space toggle   a all   n none     │

/theme, /help, the session and file pickers and the settings list already use render_panel_scroll_rail for this, so the item rows here do too. When the rail is drawn, the rows and their hitboxes give up its column: hints are truncated one column shorter, and since handle_mouse hit-tests with rect.contains, a click on the rail doesn't toggle the row next to it. A list that fits draws no rail and is unchanged.

Issue

No-Issue: /statusline gives no cue that more items are below when the list scrolls, no issue filed for it

How I tested it

• Ran a debug build in a pseudo-terminal with an empty HOME and opened /statusline at 40×12, 60×16, 80×19, 80×24 and 100×32, with this change and without it. The rail shows at 40×12 and 60×16, and End moves the thumb to the bottom; 80×19 and up fit all eleven and are byte-identical before and after.
• At 40×12, clicking the rail cell on the Model row changes nothing; clicking the column just left of it moves to Model and toggles it.
• cargo fmt --all -- --check, cargo clippy -p codewhale-tui --all-targets --all-features with CI's flags, and cargo check -p codewhale-tui --all-targets: clean. Clippy also on 1.99, plus cargo +1.89.0 check -p codewhale-tui.
• cargo nextest run -p codewhale-tui --lib: 15349 passed, none failed, including the 15 status picker tests.

Checklist

• One focused change, on db04c38; it merges cleanly into current main
• cargo fmt --all passes, and tests cover new or changed behavior
• If this adds or changes a user-facing feature, I updated its docs and its row in docs/features.toml (cargo test -p codewhale-tui --test feature_registry checks it) — n/a

Thanks @Lstarsky0. Reusing render_panel_scroll_rail brings /statusline in line with /theme, /help and the settings lists, and narrowing the row hitboxes means a click on the rail no longer toggles the row next to it. Your 40×12 captures made it quick to review. Merged in 705bf08 for 0.10.2, which hasn't shipped yet.
