fix(ui): keep tinted pill text at 4.5:1 on hovered and selected rows - #298

Conversation
Status and accent pills used the base tone as text on a 12 to 16% tint of the same tone. That passes on a plain surface, but drops below 4.5:1 when the pill sits on a pressed or hovered button (surface-3) or a selected row (accent tint). Measured on the live panel: a deferred block error pill on a hovered row was 4.34:1 in light, and the DI component letter on a selected row was 4.36:1 in light. Add per-theme text-on-tint tokens (--ok-text, --warn-text, --danger-text, --accent-text, the last from a new `text` key on each accent) and an m.tint($tone) mixin that uses them. Status and accent m.soft calls and the hand-written tone pills now use the mixin or the tokens. On brand views --accent-text follows the view accent like --accent. Analog's info pill and GET method and DI's light directive color get darker light values. A panel test compiles the theme for every accent and checks each -text token against its tint on every surface and selected row in both themes.

- Line 166: Keep `[style.--accent]` bound to `viewAccent()`, but bind
`[style.--accent-text]` to a separate per-theme text-on-tint value instead of
reusing the base accent. Ensure that value maintains at least 4.5:1 contrast
against the actual tinted backgrounds across the affected themes and modes.

Brand views set --accent-text to the brand accent itself, which drops to 3.48 to 4.24:1 on its own tint over a selected row (4.74:1 at worst for dark Capacitor). Each brand view now has a dark and a light text value next to its accent in app/src/view-accents.ts, and the panel root binds --accent-text to it. --accent is unchanged. The tint contrast test now also checks every brand view, in both themes, with the brand accent as the selected row under every pill tone.

What and why
Status and accent pills, badges and chips used the base tone as text on a 12 to 16% tint of the same tone. That passes on a plain surface but drops below WCAG AA (4.5:1) when the pill sits on a hovered or pressed button (
--surface-3) or on a selected row (accent tint), mostly in the light theme. Measured on the live panel: a deferred block error pill on a hovered row was 4.34:1 in light, and the DI component letter on a selected row was 4.36:1 in light.This adds per-theme text-on-tint tokens (
--ok-text,--warn-text,--danger-text,--accent-text) and anm.tint($tone)mixin, and moves every status and accent pill to them. Brand views (NgRx, Analog, Angular Native, NativeScript, Capacitor) get their own dark and light--accent-textfromapp/src/view-accents.ts;--accentitself is unchanged. Analog's info pill and GET method, and DI's light directive color, get darker light values. The UI guidelines describe the new tokens and mixin.Brand view accent pills, worst backdrop (selected and hovered row), before → after: dark NgRx 4.01 → 6.49, Analog 3.87 → 6.37, Angular Native 3.81 → 6.47, NativeScript 4.09 → 5.57, Capacitor 4.74 → 6.12; light NgRx 3.60 → 5.71, Analog 3.48 → 5.30, Angular Native 3.48 → 5.30, NativeScript 4.24 → 5.78, Capacitor 3.57 → 5.69.

Notes for reviewers
