### What?
This PR applies `mergeFieldStyles` to the `ArrayFieldComponent`
component, ensuring that custom admin styles such as `width` are
correctly respected when Array fields are placed inside row layouts.
### Why?
Previously, Array fields did not inherit or apply their `admin.width`
(or other merged field styles). For example, when placing two array
fields side by side inside a row with `width: '50%'`, the widths were
ignored, causing layout issues.
### How?
- Imported and used `mergeFieldStyles` within `ArrayFieldComponent`.
- Applied the merged styles to the root `<div>` via the `style` prop,
consistent with how other field components (like `TextField`) handle
styles.
Fixes#13973

### What?
This PR applies `mergeFieldStyles` to the `BlocksField` component,
ensuring that custom admin styles such as `width` are correctly
respected when Blocks fields are placed inside row layouts.
### Why?
Previously, Blocks fields did not inherit or apply their `admin.width`
(or other merged field styles). For example, when placing two Blocks
fields side by side inside a row with `width: '50%'`, the widths were
ignored, causing layout issues.
### How?
- Imported and used `mergeFieldStyles` within `BlocksField`.
- Applied the merged styles to the root `<div>` via the `style` prop,
consistent with how other field components (like `TextField`) handle
styles.
Fixes#13498
Previously, data created by other tests was also leaking into unrelated tests, causing them to fail. The new reset-db-between-tests logic added by this PR fixes this.
Additionally, this increases playwright timeouts for CI, and adds a specific timeout override for opening a drawer, as it was incredibly slow in CI
As field tests grow in size, they need to be moved out of the greater
fields test spec and into their own standalone files for readability,
maintainability, and speed. This way they we can write field tests in a
more isolated environment, and they can run in parallel in CI.
