fix: preserve filters across manual and auto refresh (#12)

Manual refresh from the Toolbar button was sending getLog without filter
state, causing the backend to drop the saved filters while the webview UI
continued to show them as active. Auto refresh via refreshAll only passed
remoteFilter to git log (branch filter was lost) and the fullRefresh
handler unconditionally reset both filter UIs.

- Toolbar now delegates refresh to an onRefresh callback so App.svelte
  can include the current branch and remote filters in the request.
- refreshAll passes both currentRemoteFilter and currentBranchFilter to
  git log and includes them in the fullRefresh payload.
- The fullRefresh handler now syncs filter UI from the payload instead
  of clearing it, so file-watcher refreshes keep filters intact while
  repo switches (which clear filters on the backend) still reset the UI.
