fix(miniapps): align rating hover states and scope text styles

[bobleer]

Summary

Fix MiniApp rating stars being offset from their hover backgrounds. Rating-summary styles now target an explicit text class instead of every descendant span, preserving the icon button's centering and color in the library, legacy market view, and standalone marketplace.

Apply the same scoping fix to customization/preview headers and detail capability descriptions so text styles no longer override close-button internals or capability titles. Shared OverflowText continues to own clipping.

Type and Areas

Type: Bug fix / UI

Areas: Web UI MiniApps and standalone MiniApp marketplace

Motivation / Impact

Hovering a rating button previously highlighted a box to the left of its star because the statistics margin also matched the button's icon span. Dedicated text classes keep spacing on the statistics and leave the icon centered in its control.

Verification

Passed locally:

• pnpm run check:web (types, Appearance, typography, theme color and visual contracts)
• pnpm --dir src/web-ui exec vitest run src/app/scenes/miniapps/components/MiniAppCard.presentation.test.ts src/app/scenes/miniapps/components/miniAppDetailPresentation.test.ts --maxWorkers=50% (17 tests)
• pnpm run type-check:miniapp-market
• pnpm run test:miniapp-market (29 tests)
• pnpm run build:miniapp-market
• pnpm run motion:audit (reviewed inventory)
• node scripts/check-git-object-sizes.mjs --base upstream/main --head HEAD
• git diff --check

Local marketplace browser verification: all five stars have zero horizontal/vertical center offset from their buttons; the third star also stays centered while hovered. Compiled CSS/DOM checks confirm that desktop rating and header text rules no longer match icon/progress spans.

Reviewer Notes

AI-assisted. Testing level: lightly tested (focused tests, build checks, and local browser inspection; no native desktop end-to-end validation). Remote workspace, remote control, Peer Device Mode, and Detached Dispatch were not exercised. This change only scopes frontend styles; it does not change persisted data or remote protocols.
