Fix: harden live overlay detector waivers (#639 follow-up)

Read waiver config from every live root (appRoot, contextRoot, repoRoot),
so monorepo projects whose config lives at the repo root reach the
overlay; serialize served roots and page identities repo-relative there.

Resolve each page URL to its actual serving file via the inject config's
resolved page list before applying file-scoped waivers; ambiguous URLs
keep the conservative common-ancestor fallback (PR #645 review
discussion r3840011436).

Honour detector.ignoreFiles: a wholly waived page now scans to zero
findings in the overlay, matching the CLI and the edit hook.

Guard the resolver call so a throwing resolver degrades to an unfiltered
scan instead of breaking the detect toggle.

Match design-system-color waivers by color value across hex and rgb()
spellings, and stop extracting font values for bounce-easing findings,
mirroring extractFindingIgnoreValue. Regenerate the browser bundle.

AI-assisted change: reviewed, planned, and implemented with Claude Code
under maintainer direction.
