* chore: Update to Rust 1.88

* chore: Fixes missed by Claude

This adds the update command to the help text output which was an
oversight from my work in #26520.

Before this commit, although `--object-store` is mandatory it is not
reflected in the error messages. The examples are listed in the issue
976.

This commit makes `object_store` explicitly required which means error
messages include `--object-store` listed as mandatory

closes: influxdata/influxdb_pro#976

- update rust version to 1.88
- remove defaulting to `file` for object store

helps: influxdata/influxdb_pro#976

* feat: Allow hard_deleted date of deleted schema to be updated

* feat: Include hard_deletion_date in `_internal` `databases` and `tables`

* feat: Unit tests for testing deleted databases

* chore: Default is now to hard-delete with default duration

* test: Update test names and assertions for new default hard deletion behavior

- Renamed delete_table_defaults_to_hard_delete_never to delete_table_defaults_to_hard_delete_default
- Renamed delete_database_defaults_to_hard_delete_never to delete_database_defaults_to_hard_delete_default
- Updated assertions to expect default deletion duration instead of None/Never
- Aligns with the change of HardDeletionTime default from Never to Default

* chore: Remove TODO

* chore: PR feedback and other improvements

* Ensure system databases and tables schema specify a timezone for the
  `hard_deletion_time` Timestamp columns (otherwise they display without
  a timezone)
* `DELETE` using `default` delay is idempotent, so multiple requests
  will not continue to update the `hard_deletion_time`
* Improved test coverage for these behaviours
