Susana Ferreira 1989db0e2b feat(coderd): enforce ai budget on pre-request path (#26915) ...

## Description

Adds pre-request AI budget enforcement to `aibridged`. Requests are rejected with HTTP 403 when the user's aggregated spend for the current period has reached their effective limit.

## Changes

- Add `IsBudgetExceeded` RPC to `aibridgedserver`. Resolves the user's effective budget, aggregates spend over the caller-supplied `[period_start, now]` window, and returns whether the limit has been reached along with the effective limit.
- Wire the check into `aibridged`'s HTTP handler. The caller computes the period start (monthly for now) and passes it in the request.
- Reject exceeded requests with HTTP 403 Forbidden and a message directing the user to contact an administrator.
- Add `dbtime.StartOfMonth` alongside `StartOfDay` for period computation.
- Add real-DB tests covering the enforcement path: month-boundary excludes prior-period spend, and a new user override unblocks a previously-exceeded user.
