refactor(e2e): move budgets and spend_tracking suites under quota_management

@@ -11,8 +11,7 @@ Each subdirectory under `tests/e2e/` is one suite, scoped to an endpoint family

 - `batches/` - the `/batches` endpoint (placeholder until the first test lands)
 - `realtime/` - realtime websocket sessions, including the pipecat audio path

+- `quota_management/` - quota enforcement and accounting, one subfolder per behavior: `budgets/` (budget definition, enforcement, and reset windows: key, team, tag, soft, multi-window) and `spend_tracking/` (spend logging and cost attribution on `/spend/*`)
 - `management/` - key/team/user/organization management routes: create/update/delete persistence via the info routes, team membership, and llm-only-key route denials; also the dashboard UI behavior on top of them, driven through the proxy-served UI at /ui with playwright (optional dep behind importorskip)
 - `logging/` - logging-integration delivery (datadog and friends)
 - `security/` - secret handling and log-leak protection
