Paul Trowbridge 55814ee0d5 Multi-slice operations, tagged bridge, and a reworked adjustment panel
Forecast operations could only act on one clicked row at a time, and the
panel that drove them separated the numbers you were reading from the
inputs that changed them. This reworks both, and adds initiative tags so
a version's history can be read as a bridge.

Operations
- Accept `slices` (array) alongside the legacy single `slice`, with
  apply_mode 'prorate' (one pool) or 'each' (independent per slice).
- buildWhereAny() ORs the slices into one predicate. A union of slices
  cannot be flattened into per-column IN lists without over-selecting,
  and the result is parenthesised so the appended exclude clause does not
  bind wrong.
- resolveIncrs() now resolves each measure independently: target, percent
  or change amount per measure, so a target on value and a percent on
  units can be submitted together. Replaces the single global `mode`.
- target_basis chooses what a target measures against: only the rows an
  operation can write, or everything the pivot shows for the slice.
  Excluded iters are visible in the grid but immovable, so a target set
  against the visible total previously overshot by their contribution.

Two latent bugs surfaced by the above, both pre-existing:
- A slice naming no filterable column reduced to TRUE and applied the
  operation to the entire version. Now rejected on all three operations.
- Prorating across a pool that nets to ~zero multiplies each row's share
  by an exploding factor, sending rows to extreme opposite values to hit
  the target. Refused when the net falls below 1% of gross.

Tags and the bridge
- pf.log gains a nullable `tag`, written by a follow-up UPDATE rather
  than through the generated SQL: those templates are stored per source
  in pf.sql, so a {{tag}} token would strand any source that had not
  re-run "Generate SQL".
- Tag is editable after the fact in the change log, with completion from
  tags already used on the source. PATCH branches on whether a field was
  sent, so a tag can be cleared as well as set.
- BridgeView renders the walk from baseline to current as a waterfall,
  one step per tag, scoped to the selection, the pivot's filters, or the
  whole version. Computed from the loaded Perspective table so the
  figures always reconcile with what is on screen; overlapping slices are
  deduped by pf_id to match the OR semantics operations use.
- Colour is a polarity job, so it uses the validated diverging pair
  (blue/red, CVD dE 21.6) with neutral anchors, not categorical hues.
  Every bar is directly labelled and a table view is available.

Panel
- Extracted to OperationPanel; the scale form is one continuous ledger:
  baseline, each adjustment, current, then New value / Change / % change
  as three interchangeable editable rows. Typing in any one derives the
  others, which removes the target/delta/percent mode toggle entirely.
- Dockable bottom, right, or floating (drag to move, grip to resize), and
  closable via header, Esc, or the toolbar. Placement persists.
- Controls no longer stretch to the dock width, and text contrast now
  clears WCAG AA against white throughout.

Also: the status bar names the physical table writes land in, with live
row counts; and the pivot's expand depth is re-applied when the tab
regains focus, since Perspective rebuilds its view on redraw and a
ROLLUP view with no depth set renders fully expanded.
