[improvement](fe) Add configurable interval for catalog recycle bin daemon
thread (#63311)
### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary: The CatalogRecycleBin daemon thread uses a hardcoded
30s interval (`DEFAULT_INTERVAL_SECONDS`), which cannot be adjusted via
FE configuration. Other master-only daemon threads like TabletScheduler
use configurable intervals via Config parameters (e.g.,
`tablet_schedule_interval_ms`).
### Release note
Add a new FE config `catalog_recycle_bin_interval_ms` to allow
configuring the catalog recycle bin daemon thread interval, default 30s.
