Hongming Wang 64822dac49 refactor(wsauth): extract lookupTokenByHash to dedup auth predicate across 3 callers
ValidateToken, WorkspaceFromToken, and ValidateAnyToken each duplicated
the same JOIN+WHERE auth predicate:

    FROM workspace_auth_tokens t
    JOIN workspaces w ON w.id = t.workspace_id
    WHERE t.token_hash = $1
      AND t.revoked_at IS NULL
      AND w.status != 'removed'

Same drift class as the SaaS provision-mint bug fixed in #2366. A
future safety addition (e.g. exclude paused workspaces from auth) had
to be applied to all three queries; a partial application would
silently re-open one auth path while closing the others.

Fix: hoist the predicate into lookupTokenByHash, which projects
(id, workspace_id) — the union of fields any caller needs. Each
public function picks what it uses:

  - ValidateToken      — needs both (compares workspaceID, updates last_used_at by id)
  - WorkspaceFromToken — needs workspace_id
  - ValidateAnyToken   — needs id

The trivial perf cost of selecting one extra column per call is worth
the single-source-of-truth guarantee for the auth predicate.

Test mock updates: two upstream test files (a2a_proxy_test, middleware
wsauth_middleware_test{,_canvasorbearer_test}) had hand-typed regex
matchers and row shapes pinned to the per-function SELECT projection.
Updated to the unified shape; behavior is unchanged.

All wsauth + middleware + handlers + full-module tests green.
