Replace 14 hardcoded per-category CSS rules with a single --cat-color
custom property set inline on each filled cell button, driven by the DB
categories list threaded from PlanWork → PlanGrid → PlanRangeChips.

Work-plan fixes from this session:
- Czech audit descriptions for plan entries/overrides (was empty '-')
- server-embedded project label on grid cells (was '-' past the 100-project cap)
- dashboard activity + audit-log cache invalidation on plan mutations
- read-only cells: no '+' on empty, keep hover on cells with a record
- view modal: Czech category + formatted dates
- sticky date column made opaque (no bleed-through on horizontal scroll)
