Pull request overview

This PR implements a vertex deletion feature for polygon and polyline annotations, adding a new configurable keybind (default: x) that allows users to delete individual vertices by hovering over them. It also fixes a bug where deleting an annotation mid-edit would leave the ULabel state stuck in edit mode.

Changes:

• Added delete_vertex_keybind configuration option with default value "x"
• Implemented vertex deletion logic with automatic cleanup (polylines with ≤1 point and polygon layers with <3 points are removed)
• Fixed state clearing bug in annotation deletion to prevent edit mode getting stuck
• Added comprehensive E2E tests for vertex deletion functionality
