Automation/Script editor border-radius fix

Breaking change

Proposed change

"Disabled bar" was overflowing.
Related to: ha-automation-condition-row, ha-automation-action-row, ha-automation-trigger-row, ha-script-field-row.
Old code was like

        .disabled-bar {
          ...
          border-top-right-radius: var(--ha-card-border-radius);
          border-top-left-radius: var(--ha-card-border-radius);
        }

w/o default values.
But even with default values it would cause artefacts.
So I removed these radiuses for .disabled-bar, .triggered, .testing and set overflow: hidden for ha-card.

before:

after:

Another issue is with undesired radius for selected ha-expansion-panel under .disabled-bar:

but have not found a good solution yet.
