v0.3 Phase 5f.1 polish: date groups, useful previews, quiet row actions

Acts on the polish-pass brief returned for 5f. Touches the quietware
branch only; v0.2 fallback (and compactPreviewText, used by its
row-height measurer) is left intact.

  Date groups       liveGroups derived walks `filtered` and breaks at
                    local-calendar-day boundaries. dateGroupLabel
                    formats Today / Yesterday / D MMM / D MMM YYYY.
                    Section headers are 11px mono uppercase, separated
                    by the same divide-y the rows use.

  Row hierarchy     New quietRowPreview returns a real transcript
                    snippet (item.text → item.preview → empty). The
                    title repeat in 5f was compactPreviewText returning
                    the title under the title; that helper stays for
                    v0.2's height math, the quietware row uses the new
                    one. Falls back to "No preview available" in-template.

  Row meta-line     HH:MM · duration · Dictation|File. Date moved to
                    the group header — repeating it per row wasted
                    hierarchy.

  Row actions       Open stays visible (tertiary), other actions moved
                    behind a quiet LumotiaIconButton(MoreHorizontal)
                    trigger that opens LumotiaMenu with Copy /
                    Export markdown / Move to Trash. Trigger is
                    always present (not hover-only) so keyboard
                    focus works.

  Search alignment  Dropped max-w-2xl. Search now spans the same
                    content gutter as the rows so the right edge
                    aligns with where the actions column begins —
                    intentional, not arbitrary.

  Trash rows        Same row anatomy. Restore visible. No overflow
                    menu — perm-delete-from-trash UI is deferred per
                    the existing comment (TRANSCRIPT_TRASH_RETENTION_DAYS
                    handles hard-removal). Meta-line shows
                    "Deleted …  ·  Auto-purges after 30 days".

Date-grouping formula (per CLAUDE.md rule):
  same local-calendar day as now → "Today"
  previous local-calendar day    → "Yesterday"
  same local-calendar year       → "D MMM"
  older                          → "D MMM YYYY"
Day boundaries are strict local midnight, not 24-hour windows. Items
without savedAt fall into an "undated" bucket.
