Scaffold Homelab Manager foundation

Monorepo (Express+TS+Drizzle/libSQL server, React+Vite+Tabler web) matching
the stack used by ScheduleTaskManager and Sloth Manager. Includes Authentik
OIDC login with local admin/operator/viewer roles (first user becomes admin),
a generalized audit log, encrypted-at-rest storage for future integration API
tokens, the DB schema for all planned modules, and the Tabler-styled app
shell/nav. Also ports the Secrets (expiry tracker) and IP Addresses (IPAM)
modules from Sloth Manager onto the new stack.
