fix(2meet-data-optimizer-hivepress-addon): let transient timeouts outlive their values; register site attributes once themes load

- review F5: a timeout entry expired before its value (a day vs a week), and
  HivePress reads a missing timeout as "never expires", serving the stale
  value for up to six more days. The timeout now expires a minute after the
  later of MAX_CACHE_TTL and its own time, so HivePress sees it expire first
- review F7: site attributes accept only types with a plain index (json and
  binary would fail the CREATE TABLE)
- review F8: the hp_listing_attrs group is registered on the run after
  after_setup_theme (init:1), so a filter added in a theme counts and the
  group has one definition per request; only keys of other groups are skipped
- Verify: TTL test, attribute group tests, unit 148, integration 53, phpcs
- PR: PR-115 (2.3 acceptance correctness review)
