### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary:
The `org.apache.doris.statistics` package mixed optimizer-facing statistics
models with collection workflows, cache internals, and statistics-table
persistence, making class ownership difficult to identify.
This PR reorganizes those classes by responsibility:
- keeps optimizer-facing statistics values, builders, ranges, and shared
constants in `statistics`;
- moves collection jobs, tasks, scheduling, metadata, and update events to
`statistics.analysis`;
- moves cache loaders, keys, invalidation, refresh, and synchronization
targets to `statistics.cache`;
- moves internal statistics-table access, persisted row models, and cleanup
to `statistics.repository`;
- mirrors the same package layout in unit tests and documents the boundaries
in `README.md` and `package-info.java`.
No runtime logic or persisted field format changes.
