Add Estonian interface translation (#294)

* I18N.et: add Estonian interface translation

* I18N.et: record the verified headless fork push step

* i18n: send interface text that skipped translation through the catalog

A test-only pseudo-language wraps every catalog lookup in ⟦…⟧ marks; a new
audit test lays the app out in it (every tab, File page, dialog and pane,
the right-click menu, and a hover and a click on every ribbon control,
including the Table and Equation tabs) and fails on any visible text
outside the marks. The document is drawn as an image, so only interface
text is checked; document text, font and style names, shortcuts, icon
lettering, contributor handles and command error messages are allowed.

What it found, now translated in every language that has the strings:
- Right-click menu items (Cut, Paste, Font…, Paragraph…, Link…, New Comment).
- Paragraph dialog: the alignment choices showed code values (`left`);
  the label now sits before the dropdown.
- Table Design › Table Style Options checkboxes.
- Table Layout › Alignment tooltips showed code values (`topLeft`).
- Design › Fonts: the theme's name is translated, its font names are not.
- `pt` units, the Insert › Table grid label, the default watermark text,
  the font dialog's preview sample, and the untitled document's name.
- Contributors and Models dialogs: headings, sort and name choices, summary.

* Draw Table and Eraser: draw tables and split or merge cells with a pen (#303)

Insert › Tables › Draw Table and Table Layout › Draw › Draw Table / Eraser.
table.draw takes a pen stroke in page points: a rectangle outside a table
inserts a one-cell table of that size at the paragraph under its start; a
straight vertical or horizontal line inside a table splits the cells it
crosses (new grid column or row; untouched cells span it). table.eraser
merges the two cells beside the border nearest a point. Each stroke is one
undo step. In the app the buttons toggle pen and eraser modes with a live
preview, a crosshair with the tool's icon, and Esc to stop; canvas clicks
don't move the caret while a tool is on. Splitting through part of a
vertically merged cell and erasing beside one are refused with a clear
error. Catalog 384/430 -> 387/430.

* Draw tab: pen, pencil and highlighter ink, stroke eraser and Hide Ink (#307)

Ink strokes are floating freeform shapes: a new Freeform geometry (paths in
shape-local coordinates, opacity, and the pen that drew it) on
InlineObject::Shape with ShapeKind::Freeform. draw.stroke inserts one
anchored to the paragraph under the first point (one undo step; points
capped per stroke, strokes capped per page, NaN dropped); draw.erase /
draw.eraser with a point deletes the stroke under it; draw.pen, draw.pencil,
draw.highlighter, draw.eraser and draw.select set the Draw tab's tool in the
session view state; review.hideInk toggles showing ink on screen.

The canvas draws a live stroke while a pen is dragged and commits it on
release; the eraser deletes strokes it passes over (one undo step per drag);
Esc or Select goes back to selecting. Draw tab buttons show the tool in use,
with colour and thickness menus; Review gets an Ink group with Hide Ink.
Ink renders with round caps and joins on screen and in PDF; highlighters are
translucent and behind the text. DOCX writes freeforms as wps:wsp with
a:custGeom (moveTo/lnTo) in a wp:anchor and reads them back, along with
simple custom-geometry freeforms from other files.

* #315 review fixes: eraser undo test, sanitized tap dots, custGeom path cap, ink docs

- draw.eraser with a point erases through draw.erase: test that it is one
  undo step (undo/redo) and marks the document dirty.
- Render and PDF: a single-point stroke's dot is drawn at the sanitized
  point, not the raw first one.
- DOCX custGeom reading stops once MAX_PATHS paths (subpaths included) are
  collected, across a:path elements.
- docs/file-format-parity.md: ink is saved as custom geometry, not InkML, so
  Word shows it as a freeform.
- widgets test: theme::apply takes an Appearance (#317).

* #313: catalog rows for the newly translated interface text

Rows in all eight catalogs for the strings #313 now sends through the
catalog (cell alignment tooltips, credits columns and summary, theme names,
context-menu items, table picker, pt suffix, Document1, the Font dialog
sample) and for the Table Style preview's sample table, which the
untranslated-text audit flagged after main's table style editor landed.
The audit runs headless (no host services: no file pickers or speech) in
about 20 s, so it stays enabled.

* i18n audit: run on demand (#[ignore]) until its rare failure under load is understood

It failed once in ~46 runs on a heavily loaded machine and passed 35 straight reruns,
so CI shouldn't depend on it yet. Run it with --ignored.
