EthanHealy01 5b5e922069 Make the upgrade banner neutral instead of gradient purple (#7696)
## What

The `promo` banner tone was a full-bleed `indigo-500 → purple-500`
gradient with white text and a black drop-shadow on the CTA. It was the
only saturated fill in the app, and against the warm neutral palette it
read as a foreign object above the workbench.

The bar is now app chrome:

| | Before | After |
|---|---|---|
| Background | 135° indigo→purple gradient | `--c-bg-raised` |
| Border | `transparent` | `--c-border-subtle` hairline |
| Icon | white glyph, no container | neutral glyph in a
`--c-surface-sunken` chip |
| Text | forced white | `--c-text` / `--c-text-muted` |
| CTA | `premium` accent (violet gradient) | `default` accent (same
primary button as the rest of the app) |

Only caller is the friendly variant of `UpgradeBanner` (self-hosted,
under the free-tier user limit).

## Notes

- **No new theme tokens.** Every value is an existing `--c-*` semantic
token, so light and dark both follow automatically with no per-theme
overrides.
- The `premium` accent itself is untouched, so the upgrade CTAs in
`OfflineActivationCard` and `PairingPanel` are unaffected.
- `--c-hue-indigo` / `--c-hue-purple` are still used by
`SaaSOnboardingSlides`, `PaygFree` and `UpgradeModal`, so no tokens are
orphaned.
- Deleted comments describe rules that no longer exist (the gradient,
the white-on-gradient text overrides, the CTA shadow). No new comments
added.

## Verification

- `task frontend:check:all` passes (typecheck, oxlint, all four theme
linters, stylelint, format, tests, build, storybook build).
- `task frontend:storybook:a11y:changed` passes light and dark: 7
AppBanner stories, 0 violations. Both a11y baselines are empty, so this
is zero known violations rather than a baselined pass.
- Checked in Storybook under **Shared / AppBanner → All Top Bars**,
which renders every top bar the app can show side by side, in both
themes.
