Typos fix (#12666)

# Typos Fix

## Description
This pull request addresses and corrects typos in two files:
- `CHANGELOG.md`: Fixed "requset" to "request".
- `up.sql`: Fixed "defaul" to "default".

## Changes
- Improved documentation and comments by correcting minor spelling
errors.
- Adjusted wording for better clarity and accuracy.

## Testing
These changes are non-functional and impact only documentation and
comments. No tests are required, and all existing functionality remains
unchanged.

## Notes for Reviewers
Please verify that the corrections align with the project's style and
guidelines. Let me know if additional adjustments are needed. Thank you!
