perf(frontend): split admin bundles and tighten data fetching

Add next/dynamic lazy loading for database, logs, and settings heavy
modules; migrate access-logs and task-executions to React Query; parallelize
login auth-sources with public config; consolidate users table tooltips;
enable lazy image decoding; and replace barrel @/lib/services imports with
direct module paths.
