v0.2.26 Machine control, engraving and editing fixes

• Stop, pause, disconnect and reconnect handle controller failures more reliably. Unconfirmed stops ask you to use the physical stop.
• Fill power scales, cutting order, rotated raster scans and transparent images preserve the intended output.
• Edits, imports and settings recovery preserve data. Late replies cannot change another project or camera, and slow operations keep the window responsive.
• Camera overlays require a machine profile. Job checks and connection errors use the selected language and units. Outlined SVG text uses a bundled font when system fonts are unavailable.

GRBL over Network remains Experimental. See Software update for installation instructions.
