Search and sort the games list

[engleek]

Fixes #206. (Rebuilt on main now that #229 is merged: a single commit.)

/games could only be filtered by tag, and always listed recently updated games first.

Change

• Search (?q=): debounced (300 ms). It matches the name or the description, case-insensitive (Prisma contains, mode: 'insensitive'). I chose that over the full-text helper because it combines simply with the tag ANDs. Blank means no search.

• Sort (?sort=):

  • updated, recently updated: the default, and the old order;
  • newest, recently added;
  • name, name A–Z.

  orderBy is picked from a whitelist, so unknown values fall back to the default. An id tiebreak keeps infinite-scroll pages from overlapping when values tie.

• Tag filters keep q and sort when toggled. Before, setSearchParams({ tags }) dropped every other parameter.

• Tag counts follow the search, since they share its where.

• Layout: the search box and sort select sit above the tag filter. On a phone they wrap with no horizontal scroll; I checked at 375px.

Tests

A new e2e test:

• checks ?sort=name orders the cards A–Z and the select shows it;
• types a word from a game's name: the URL gains q, keeps sort, and only matching games remain;
• toggles a tag, which keeps both q and sort;
• checks ?sort=bogus still renders;
• scrolls to load the next page and checks the whole list is still in name order.

On main: it fails. Locally: the full e2e suite (39) and the unit and story tests (51) pass.
