Lei, HUANG 69870e2762 fix(mito): use 1day as default time partition duration (#6202)
* fix unit tests

* fix: sqlness

* fix/default-time-window:
 ## Add Helper Functions and Enhance Compaction Tests

 - **Refactor Compaction Logic**: Introduced helper functions `flush` and `compact` in `compaction_test.rs` to streamline compaction operations.
 - **Enhance Compaction Tests**: Added a new test `test_infer_compaction_time_window` in `compaction_test.rs` to verify compaction time window inference.
 - **Testing Improvements**: Added `#[cfg(test)]` attribute to `new_multi_partitions` in `time_partition.rs` to ensure it's only included in test builds.

* fix/default-time-window:
 - **Refactor `TimePartition` Struct**: Removed unnecessary comments regarding `time_range` in `time_partition.rs`.
 - **Enhance `TimePartitions` Functionality**: Added a method `part_duration_or_default` to provide a default partition duration in `time_partition.rs`.
 - **Update SQL Test Cases**: Modified SQL operations and expected results in `scan_big_varchar.result` and `scan_big_varchar.sql` to reflect changes in data manipulation logic.

* fix/default-time-window:
 ### Update Time Partition Default Duration

 - **Refactor Default Duration**: Introduced `INITIAL_TIME_WINDOW` constant to define the default time window duration as `Duration::from_days(1)`. This change replaces multiple instances of the hardcoded default duration across the `time_partition.rs` file.
 - **Files Affected**: `time_partition.rs`

* fix/default-time-window:
 ## Update Partition Duration Handling

 - **`time_partition.rs`**: Refactored `part_duration` to be non-optional, removing `Option` wrapper. Updated logic to use `unwrap_or` with `INITIAL_TIME_WINDOW` where necessary. Adjusted related methods and tests to accommodate this change.
 - **`version.rs` (memtable and region)**: Updated handling of `part_duration` to align with changes in `time_partition.rs`, ensuring consistent use of non-optional `Duration`.

* fix/default-time-window:
 ### Improve Error Context in `time_partition.rs`

 - Enhanced error context message in `time_partition.rs` to provide clearer information on partition time range issues, including bucket size details.
