feat(plugins): add sorting, filtering, and fix Update All button (#252)

* feat(store): add sorting, filtering, and fix Update All button

Add client-side sorting and filtering to the Plugin Store:
- Sort by A-Z, Z-A, Verified First, Recently Updated, Category
- Filter by verified, new, installed status, author, and tags
- Installed/Update Available badges on store cards
- Active filter count badge with clear-all button
- Sort preference persisted to localStorage

Fix three bugs causing button unresponsiveness:
- pluginsInitialized never reset on HTMX tab navigation (root cause
  of Update All silently doing nothing on second visit)
- htmx:afterSwap condition too broad (fired on unrelated swaps)
- data-running guard tied to DOM element replaced by cloneNode

* refactor(store): replace tag pills with category pills, fix sort dates

- Replace tag filter pills with category filter pills (less duplication)
- Prefer per-plugin last_updated over repo-wide pushed_at for sort

* debug: add console logging to filter/sort handlers

* fix: bump cache-buster versions for JS and CSS

* feat(plugins): add sorting to installed plugins section

Add A-Z, Z-A, and Enabled First sort options for installed plugins
with localStorage persistence. Both installed and store sections
now default to A-Z sorting.

* fix(store): consolidate CSS, fix stale cache bug, add missing utilities, fix icon

- Consolidate .filter-pill and .category-filter-pill into shared selectors
  and scope transition to only changed properties
- Fix applyStoreFiltersAndSort ignoring fresh server-filtered results by
  accepting optional basePlugins parameter
- Add missing .py-1.5 and .rounded-full CSS utility classes
- Replace invalid fa-sparkles with fa-star (FA 6.0.0 compatible)

* fix(store): semver-aware update badge and add missing gap-1.5 utility

- Replace naive version !== comparison with isNewerVersion() that does
  semver greater-than check, preventing false "Update" badges on
  same-version or downgrade scenarios
- Add missing .gap-1.5 CSS utility used by category pills and tag lists
