## Description
<ins>Problem</ins>
When editing the Computed Value field of a column in the Table widget, a
closing round bracket `)` is automatically removed from specific
expressions upon losing focus, leading to broken expressions and
incorrect widget behavior.
<ins>Root cause</ins>
Incorrect handling of double curly braces and nested parentheses in the
`computedValue` parsing logic.
<ins>Solution</ins>
This PR handles the correction of expression parsing in
`ComputeTablePropertyControlV2` by updating the extraction logic to
support nested parentheses correctly. It also includes a test to ensure
this functionality works as expected.

## Summary by CodeRabbit
- **Bug Fixes**
- Improved handling of malformed expressions in table computed value
inputs, resulting in more consistent error output.
- Enhanced default computed value behavior to provide a fallback when
table data is empty, preventing errors.
- **Tests**
- Updated and expanded test cases for computed value extraction,
including new input variations and revised expectations for malformed
expressions.
- **Chores**
- Added a migration step to update older computed values for correct
display in widgets.
- Incremented DSL version to include latest migration updates.
