Add a staff-only Django form for editing operational host settings while keeping
host identity stable. Support address, enablement, SSH/source overrides,
include/exclude lists, rsync extra args, and retention settings using the same
SQL-backed HostConfig model consumed by backup and scheduler flows.
Parse newline-separated list fields into JSON lists, preserve nullable
excludes_replace semantics, and cover rendering plus update behavior with view
tests.
Add a staff-only Django form for creating and updating host schedules using the
SQL-backed ScheduleConfig model. Link the form from host detail pages, validate
cron expressions with the existing scheduler parser, and preserve scheduler/CLI
behavior by writing to the same source of truth.
Cover default rendering, schedule creation, updates, and invalid cron handling
with view tests.
