refactor: improve env vars editor layout and copy in MCP modal

- Replace antd Space with flex div in EnvVarsSection for more reliable
  column alignment between header and rows
- Use explicit flex styles on name/value Form.Items so columns line up
  with the Scope and remove-button columns
- Shorten "Per-user field" option label to "Per-user" and update
  disabled value placeholder to "Defined per user" for clarity
- Tweak FillUserFieldsModal description copy to better introduce the
  list of required per-user credentials
