feature: sortable player role rank in search

[lukepolo]

Adds a sortable integer role_rank to the Typesense players collection, so the player directory can sort by privilege. Today it can only sort alphabetically by role name.

• roleRank(role) returns the role's position in the existing roleOrder (user 0 … administrator 6; unknown or null is 0).
• The players schema gains role_rank (int32, sortable), and every player upsert sets it. role is unchanged.
• The boot-time schema reconcile adds the field in place (no drop or recreate) and queues a full reindex.

Merge/deploy: after deploy, run "Reindex Search" by hand (Settings → Application → Players) and wait for it to finish before merging web#613. The reindex queued at boot can be picked up by the old pod.

Tests: feature only, no bug fix. The schema, upsert and ordering tests fail when role_rank is removed or ranked alphabetically. Based on DEAFCS 476dff9, c1d91b7
