(feat) Patient banner styling refinements (#1284)

* (feat) Patient banner styling refinements

Refines the Patient Banner layout and visual consistency with the following changes:

- Sets an explicit height for the Actions menu button to ensure consistent vertical alignment (explicitly sets it to `3rem` instead of `2.5rem` from Carbon).
- Adds a top border to the contact details panel, eliminating the need for consuming components to add their own.
- Adds row gap to demographic elements (patient name and identifiers) to maintain consistent spacing when their content overflows.
- Adds right-edge padding to the patient info section to prevent the overflow menu from touching the container edge.

These changes support https://openmrs.atlassian.net/browse/O3-4114, which will refactor Patient Management repo's patient banner implementations to use shared banner components from the styleguide.
