- ComposeModal now replaces variables with actual user/tenant data when inserting signature

- Add RichTextEditor component with TipTap (ProseMirror-based) editor
- Full toolbar: bold, italic, underline, strikethrough, H1/H2/H3, bullet/numbered lists,

- Add frontend decodeMimeHeader() utility for already-stored encoded subjects (MailList + MailDetail)

drag-to-resize via mouse events, no external dependencies

three panes (folder tree, mail list, mail detail)

is now integrated into the folder tree
- Restructure MailFolderTree to show mail accounts as top-level nodes
with folders nested underneath, built from flat list via parent_id

tree works

account selector
