feat: human-readable test names everywhere + credential hygiene in logs and mocks

- TestDisplayNameGenerator registered as the global JUnit display-name
  generator: every test without an explicit @DisplayName gets a readable
  sentence (testAllInvitationWithQuery -> 'All invitation with query',
  verb-led names get a 'should ...' prefix). Explicit annotations still win.
- Security sweep fixes:
  - preserve-mode log no longer prints the management token value
    (CI console is org-visible); only a 6-char prefix is shown
  - replaced a personal gmail address in OrgApiTests with example.com
  - replaced a blt-format uid in mockrole/updateRole.json with a placeholder

Verified: dynamic suite 252/0 failures; report shows 0 old-style names;
leak scan of report and tracked sources: no authtokens, cs* tokens,
passwords or real uids.
