Code-review findings:
- donation-toast: restore path/secure/sameSite cookie attributes the
inlined useCookie dropped (security/scope regression).
- utils/color: restore @uiw fallback so percentage-notation rgb() still
converts (custom style-rule colors are arbitrary strings); add tests
pinning the one real difference vs the black fallback.
- knip: drop stale npm-check-updates ignoreDependencies entry.

Finding 1: Replace hand-rolled MONTH_NAMES[12] array with Intl.DateTimeFormat("en-US", {month:"long"}).
Finding 2: Drop @uiw/color-convert fallback — parseColorString already rejects the same inputs, return "#000000" instead. Remove dep from utils and server package.json.
Finding 3: Replace 56 z.literal calls in z.union with z.enum([...]); identical parse behavior and inferred type.

* feat(editor): add multicolor highlight with auto-contrast text
Enable the Tiptap Highlight extension in multicolor mode, replacing the
single-color yellow toggle with a full color picker (16 presets + custom).
When the chosen highlight color is perceptually dark, text inside the mark
automatically renders white for readability.
Changes span the full pipeline:
- Editor: ColorPicker UI, extended renderHTML for contrast detection
- PDF: normalizeMarkElements preserves data-color as inline style
- DOCX: mergeStyle reads actual background-color from <mark>
- Utils: new isDarkColor() luminance helper
Backward-compatible: legacy <mark> without data-color still renders yellow.
Resolves#3109
* fix: handle multicolor highlight edge cases
