Fix status bar cursor updates when opening files

[jkaunert]

Description

Fixes the status bar cursor-position label when files are opened from the project navigator, including the first file after workspace launch and subsequent tabs opened in the same workspace.

The label could show unresolved cursor positions such as Line: -1 Col: -1, or fail to refresh after opening another tab, because the status bar could read cursor state before the source editor had resolved range-based cursor positions to line/column values.

This change:

• preserves the default cursor position when the source editor has not emitted cursor state yet
• avoids replacing missing source-editor cursor state with an empty cursor array
• resolves range-based cursor positions through the existing editor range translator
• refreshes the cursor label when the active editor, selected tab, or editor controller lifecycle changes
• recreates the line label when the selected editor instance changes
• adds a focused UI regression test that opens README.md, opens LICENSE.md, verifies resolved line/column text, and clicks in the editor to confirm the label updates
