fix(schema): add missing examples to LDAP request body schema properties

Resolves oas3-missing-example vacuum lint violations that caused the
'Should be a completely valid schema' CI test to fail.

Missing example values in request body schemas for:
- /settings/ldap/test POST: add examples for bindPassword, tlsVerify, starttls
- /settings/ldap/test-auth POST: add examples for serverUrl, bindDN,
  bindPassword, searchBase, userAttribute

These 4 oas3-missing-example warnings caused vacuum lint to fail with
--fail-severity=warn (-n=warn).
