- derivePublicStatus gains optional hasActivePermanentTenancy flag;
precedence updated to "sold > under_offer > available" where
Sold can come from EITHER berths.status='sold' (admin set) OR an
active permanent-class tenancy (only when module enabled).
- Permanent-class tenure types defined in one place
(isPermanentTenureType): permanent | fee_simple | strata_lot.
Seasonal / fixed_term tenancies do NOT flip — they fall through to
the existing under_offer / available precedence.
- /api/public/berths (list) + /api/public/berths/[mooringNumber]
(single) both gate the lookup on isTenanciesModuleEnabled(portId).
Disabled module = lookup skipped entirely, preserving pre-module
behaviour for ports that haven't opted in.
- 8 new unit tests covering: flip from available, flip from under_offer,
explicit sold idempotency, false-flag fallthrough, default-omit pre-
module behaviour, permanent-class membership for each tenure type,
and null/undefined/unknown rejection.
Verified: tsc clean, 1493/1493 vitest.
