## What kind of change does this PR introduce?
Chore that resolves DEPR-399.
## What is the current behavior?
The cron jobs table in Studio uses a fixed-width `Name` column, which
can truncate long job titles and make them hard to read on
`/project/:ref/integrations/cron/jobs`.
## What is the new behavior?
The cron jobs table now allows resizing the informational columns,
including `Name`, `Schedule`, `Last run`, `Next run`, and `Command`,
while keeping the `Active` and `Actions` columns fixed-width.
This also gives the `Name` column a sensible minimum width so it can be
resized without collapsing.
## Additional context
Adds a small regression test around the cron jobs column configuration
to verify that:
- informational columns are resizable
- utility columns remain fixed
- the `Name` column has a non-zero minimum width
