Feature/UI polish

UI Polish

Description

• Hovering a spatial annotation now draws a white outline that hugs its shape.
• Polish and update the confidence card to include the class name and fix its positioning.
• Fix shift-hover to properly start a new polygon complex layer
• Fix bitmask moves to the image edge that were permanently truncating the mask. Now a translated mask bounces back to its previous position if it would be moved outside the image bounds.
• Improve read-only subtask handling. Subtasks marked read_only: true now actually prevent edits. Additionally, all subtasks may now be read-only (the previous "at least one non-read-only subtask" error has been removed).

PR Checklist

• Merged latest main
• Version number in package.json has been bumped since last release
• Version numbers match between package package.json and src/version.js
• Updated documentation if necessary (currently just in api_spec.md)
• Added changes to changelog.md

Breaking API Changes

Bitmasks will no longer trim to the image edge when translating outside the image boundaries
Read-only now is actually read-only

• Annotation IDs are only unique within a subtask, so comparing only the current hover ID can outline an inactive annotation that happens to have the same ID when all subtasks are redrawn. Also verify that the drawn annotation object belongs to the current subtask.

        return this.subtasks[subtask_key]["state"]["hovered_annid"] === annotation_object["id"];

• At non-integer zoom levels, recording the raw delta makes undo asymmetric with ULabelMask.translate rounding: for example, 0.5 moves one pixel, while the recorded -0.5 undo rounds to zero. Translate and record the already-rounded displacement so valid bitmask moves always round-trip.

            this.translate_bitmask(annotation, diffX, diffY);
