Rename internal variant values from 'personal'/'team' to 'skipper'/'admiral',
aligning code with user-facing tier names. Variant type is now resolved once
at activation/validation and stored in DB via license_variant_type, instead
of string-matching the Lemon Squeezy variant_name on every read. Also captures
variant_id for future lookups. Pre-existing installs auto-migrate on first
getVariant() call.
Eliminate all references to "Pro" across backend, frontend, and docs.
Internal tier value renamed from 'pro' to 'paid'; user-facing text now
uses the thematic tier names (Community, Skipper, Admiral).
- Rename LicenseTier 'pro' to 'paid' in backend and frontend types
- Rename requirePro guard to requirePaid, error code PRO_REQUIRED to PAID_REQUIRED
- Rename ProGate.tsx to PaidGate.tsx with updated copy
- Fix: trial users can now see upgrade/purchase cards in Settings
- Update all docs and openapi.yaml to use correct tier names
* feat(license): distributed license enforcement across multi-node setups
The primary instance's license tier is now asserted to remote nodes on
every proxied HTTP and WebSocket request via trusted headers. Remote
nodes honor the assertion only when the request carries a valid
node_proxy JWT, preventing unauthorized elevation from browsers or API
tokens. Falls back to local license tier for direct access.
* fix(test): remove unused vi import in distributed-license tests
