chore(v2): OSS v2 query API: add, fix, cleanup:

- Adds missing examples for v1-compatible /query
- Fixes curl params in examples
- Removes unsupported async option from examples
- Updates terms for consistency with branding and influxdb3 docs
- Copies the missing POST /query operation from swaggerv1compat to the v2 ref.yml
- Effectively removes the separate v1-compat spec, and adds redirects and tags for v1-compat endpoints in v2/ref.yml
- Updates affected links
