fix: pre-release UI bug batch

- Budget table column alignment: the NAME data cell had
  `display: flex` directly on the <td>, which pulled it out of the
  table-layout and desynced the column widths between data rows and the
  AddItemRow. Moved the flex wrapper into a <div> inside the cell.
  Closes #759
- Packing list: template-apply and bulk-import handlers called
  `window.location.reload()` to refresh the list, which re-rendered the
  whole trip loading screen. Both flows now merge the returned items
  into the trip store instead. Closes #760
- Journey timeline: move-up / move-down arrows were rendered on
  skeleton suggestions — skeletons are places from the linked trip and
  don't participate in sort order. Skip canReorder when
  entry.type === 'skeleton'. Closes #763
- Journey public view: the synthetic `[Trip Photos]` and `Gallery`
  entries produced by syncTripPhotos were leaking into the public
  timeline and map. The owner view already strips these in
  JourneyDetailPage — apply the same filter on JourneyPublicPage.
  Gallery photos still come from every entry so a shared gallery keeps
  showing the trip-synced photos. Closes #764
- Journey thumbnails: public gallery grid was loading the original
  asset for every tile. `photoUrl()` now takes an optional kind and the
  grid requests `thumbnail`; the lightbox still opens the original.
  Synology thumbnail default bumped from `sm` (240px) to `m` (320px)
  because `sm` looked pixelated on retina. Closes #761
