Kyle Isom 9cba3241e8 Add SQLite persistence and write-through gRPC mutations
Database (internal/db) stores listeners, routes, and firewall rules with
WAL mode, foreign keys, and idempotent migrations. First run seeds from
TOML config; subsequent runs load from DB as source of truth.

gRPC admin API now writes to the database before updating in-memory state
(write-through cache pattern). Adds snapshot command for VACUUM INTO
backups. Refactors firewall.New to accept raw rule slices instead of
config struct for flexibility.
