frontend: fix pagination styling, patient-sheet header, message avatars

- Patients pagination: render the prev/next + page-number controls as COSS
  Buttons inside the Pagination structure. PaginationLink drops its
  buttonVariants styling when given a `render` prop, so the controls were
  unstyled and wrapping; using Button restores proper pill/number buttons.
- Patient detail sheet: move the action buttons (Download summary / Transfer /
  Edit / Delete) to their own wrapping row beneath the identity block so the
  patient name is no longer truncated on the narrow sheet.
- Messages thread: add sender/recipient avatars (MessageAvatar) at the bottom
  of each message group, with a spacer to keep stacked bubbles aligned.
