♿️(frontend) Keyboard focus Fixes for docs Tree/Editor

[Ovgodd]

Purpose

Improve keyboard focus management in the docs tree/editor flow: auto-focus title on open, Escape returns focus to the correct tree item, and EmojiPicker Escape returns focus to the originating tree item, including sub-doc cases.

Proposal

• Focus title only when appropriate (avoid focus traps when re-opening a doc)
• F6 from editor/title returns focus to the right tree item (selected/focused/root)
• EmojiPicker Escape returns focus to the correct tree row (including sub-docs)
• Centralize CSS selectors in a single cssSelectors object for reuse
