test(smoke): fix three stale assertions surfaced by triage

- 01 calculator: page lives at /calculator/ (confirmed live), not
  /reconstitution-calculator/ — the 404 failed all 3 calc tests.
- 00 homepage: brand title is 'Peptide Repo' (with space); regex /peptiderepo/i
  never matched. Broadened to /peptide ?repo/i.
- 03 admin: required-plugin slug is 'prautoblogger' (WP dir), not 'pr-autoblogger'.

These were test bugs, not site regressions — the site serves all three correctly.
