feat(board): size a worded copy chip to its label, not to the icon square

[Jammy2211]

Reported from a laptop against the health board: under the Evidence gaps heading, the one-tap clear them all button reads as a thin column of text.

The cause

button.copy is a fixed 2.6rem square — exactly right for the bare clipboard glyph every board puts beside a row, and a trap for a button that carries words. At 42px wide the label wraps to one word per line and overflows its own 42px height.

Every sibling board emits only the bare glyph, so the health board — the one place in the family that gives a copy button a worded face — is where it showed up.

The fix

An opt-in modifier beside the existing button.copy.term:

button.copy.text{width:auto;height:auto;max-width:100%;padding:.34rem .62rem;
 font-size:.85rem;font-weight:600;white-space:nowrap;overflow:hidden;
 text-overflow:ellipsis;vertical-align:bottom}

Sized to the label, held on one line the way .pill is — elided rather than allowed to push the page sideways, with the same vertical-align:bottom that overflow:hidden's baseline shift needs. Being opt-in, every bare-glyph button in every board keeps the square it was drawn for.

Verification

• pytest tests/test_board_theme.py tests/test_board.py tests/test_intake_dashboard.py → 141 passed.
• Tenant firewall clean (repos_sync.py --check --only "tenant firewall (organ code)").

Companion: PyAutoLabs/PyAutoHeart#192 adds the class at the two call sites. Either order is safe — the class without the rule renders exactly as today.
