oidc groups: store and expose the OIDC groups claim
Add a Groups column on the User model populated from the OIDC
'groups' claim at login, and surface it through the gRPC/REST
User message so external tools (Headplane) can read group
membership without reaching into the database.

- proto: add 'repeated string groups = 9' to v1.User.
- types.User: Groups text column, GetGroups/SetGroups JSON helpers,
  FromClaim populates from claims.Groups. The existing
  FlexibleStringSlice on OIDCClaims.Groups already handles
  JumpCloud-style single-string emission.
- types.User.Proto(): populate v1.User.Groups via GetGroups().
- db migration 202505141323: add the column BEFORE the existing
  202505141324 migration that loads users via the struct, so the
  schema is in place before any migration touches the User type.
- db migration 202507021200: extend the inline CREATE TABLE users
  and INSERT INTO users ... SELECT FROM users_old to carry the
  new column through the SQLite schema-recreation step.
- schema.sql: declare the column so squibble.Validate accepts
  databases produced by the new migration chain. Verified against
  all 7 historical sqlite dumps in hscontrol/db/testdata/sqlite.
- types.UserView, types_clone.go: regenerated to expose Groups.
- config-example.yaml, docs/ref/oidc.md: note the 'groups' scope
  and the role the column plays for external integrations.
- integration/oidc_groups_test.go: verify the round-trip via
  headscale.ListUsers() for users with multi-group, single-group,
  and empty group memberships.

-- The following three UNIQUE indexes work together to enforce the user identity model:
--
-- 1. Users can be either local (provider_identifier is NULL) or from external providers (provider_identifier set)
-- 2. Each external provider identifier must be unique across the system
-- 3. Local usernames must be unique among local users
-- 4. The same username can exist across different providers with different identifiers

-- Examples:
-- - Can create local user "alice" (provider_identifier=NULL)
-- - Can create external user "alice" with GitHub (name="alice", provider_identifier="alice_github")
-- - Can create external user "alice" with Google (name="alice", provider_identifier="alice_google")
-- - Cannot create another local user "alice" (blocked by idx_name_no_provider_identifier)
-- - Cannot create another user with provider_identifier="alice_github" (blocked by idx_provider_identifier)
-- - Cannot create user "bob" with provider_identifier="alice_github" (blocked by idx_name_provider_identifier)
