fix: kanban not loading on refresh + modal horizontal scroll + lt-kv-row CSS

Kanban restore bug:
- set-view-mode click handler called populateKanbanCards() directly but never
  called setViewMode(), so ticketViewMode was never saved to localStorage
- DOMContentLoaded restore checked ticketViewMode (never written) — it should
  check lt_activeTab_<path> which lt.tabs.init() actually saves
- Fix: delegate to setViewMode() from the click handler; DOMContentLoaded
  reads lt_activeTab_<path> and calls populateKanbanCards() when tab-kanban

Settings modal horizontal scroll:
- .lt-modal-body was missing overflow-x: hidden; content wider than the modal
  (e.g. kbd elements with white-space: nowrap) caused horizontal scrollbar
- Added overflow-x: hidden + min-width: 0 to .lt-modal-body

Missing lt-kv-row / lt-kv-label / lt-kv-value CSS:
- These classes were used in TicketView, DashboardView, admin views but had
  no primary CSS rules (only a light-theme color override existed)
- Without rules, lt-kv-row divs were block-level grid children consuming one
  grid cell each, making lt-kv-label/value stack inside wrong columns
- Added display:contents on lt-kv-row so children participate directly in
  the lt-kv-grid 2-column grid; lt-kv-label/value get padding, border, and
  min-width:0 + overflow-wrap:break-word to prevent grid column blowout
