feat: update API URLs from /aibridge to /ai-gateway (#26567)

## Description

Updates frontend and Go SDK client URLs from `/api/v2/aibridge/*` to `/api/v2/ai-gateway/*` to match the new route aliases introduced in #26475.

## Changes

- Update `site/src/api/api.ts` to call `/api/v2/ai-gateway/*` for all AI Gateway endpoints
- Update `codersdk/aibridge.go` type comment to reference the new path
- Regenerate `site/src/api/typesGenerated.ts`

Closes https://linear.app/coder/issue/AIGOV-230
