🐛 Fix missing text in legacy SVG board thumbnails (#11552)
* 🐛 Fix missing text in legacy SVG board thumbnails

Board thumbnails rendered by frame-imposter used React's
renderToStaticMarkup, a synchronous pass with no live DOM to measure
text against. Text shapes without a persisted position-data value
therefore rendered as nothing, so a cached board thumbnail silently
lost its text until the board was hovered, selected, or the canvas
was zoomed past 130%, all of which bypass the cached thumbnail in
favor of live content.

frame-imposter now provides the same is-render? context the
standalone exporter already sets, so text without position-data
falls back to the synchronous foreignObject renderer instead of
rendering nothing.

Thumbnails cached before this fix stay broken until something
regenerates them, so on each page load, board thumbnails containing
text are opportunistically regenerated once per browser (tracked via
local-storage) so existing files self-heal without requiring an
edit.

* ♻️ Use a transducer in heal-stale-text-thumbnails

Fixes a PR review comment: the frame filtering/mapping was spread
across four separate rx operators. Collapse it into a single
transducer pass over frame-ids, leaving only one rx/map to perform
the mark-healed side effect and build the update-thumbnail action.
