After tab-completing a mention, the cursor was placed before the
completion instead of after it. The root cause: Lexical's DOM
reconciliation after document.execCommand("insertText") would lose
the browser-set cursor position. Added requestAnimationFrame-based
cursor repositioning that first tries the original text node, then
falls back to searching for the mention text in the DOM.
Also normalizes editor content padding for consistent mention dropdown
positioning.

- Use a ref for mentionState so selectMention always reads the latest
value (prevents stale-closure "blink" on click/Enter/Tab)
- Add explicit space key handling to dismiss the popup immediately
- Move Escape handler outside filteredMentions check so it always works
- Sync mentionStateRef on all state transitions

The old approach used document.execCommand("insertText") to directly
manipulate the contentEditable DOM, but MDXEditor (Lexical) reverted
these changes during reconciliation causing the "blink" bug.
Fix: work at the markdown string level instead — find the @query in
the markdown, replace it with @Name, and update via setMarkdown().
Also add an input event listener alongside selectionchange for more
reliable mention detection (fixes space-to-dismiss).

Introduce MarkdownEditor built on @mdxeditor/editor with headings,
lists, links, quotes, image upload with drag-and-drop, and themed CSS
integration. Add asset image upload API (routes, service, storage) and
wire image upload into InlineEditor multiline mode, NewIssueDialog,
NewProjectDialog, GoalDetail, IssueDetail, and ProjectDetail
description fields. Tighten prompt template editor styling.
