* fix(api-manager): allow empty combo restrictions
Represent unrestricted Combo access explicitly as combo/* so an empty Allowed Combos list can deny every Combo without affecting direct model routes. Preserve existing keys through migration 149 and cover Dashboard, policy, routing-target, and migration behavior.
* docs: sync migration count to 149 after api-key combo-access migration
Merging release/v3.8.50 forward landed 149_api_key_combo_access.sql,
bumping the real migration count from 148 to 149. Updates README.md,
AGENTS.md, llm.txt (root + all 42 i18n mirrors, exact-copy requirement)
so the strict docs-counts-sync gate matches the live count again.
