refactor(utils): replace MONTH_NAMES array, drop @uiw/color-convert, use z.enum for localeSchema

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.
