A richer record timeline: formatted notes and email, signatures, task assignment, reminders and pinning

The activity timeline on every record just grew up. Notes, calls and meeting logs now use a full rich-text editor - bold, headings, bullet and numbered lists, quotes, tables, links and inline images - so an account note reads like a proper document instead of a wall of plain text. Composing an email from a record is the same Gmail-class experience: formatting, images you drag or paste (uploaded and hosted so they show up in the recipient's inbox), and a live preview of what you send. Signatures are built in and layered: set your own in your Profile with variables like {{user.name}}, {{user.title}}, {{user.phone}}, your photo and your booking link, and choose to auto-add it to new emails - while admins set a workspace-wide signature and per-team signatures in Settings → Email, so everyone stays on-brand with their own details filled in automatically. Tasks can now be assigned to a teammate (they get a notification and can filter their Tasks page to "Assigned to me") and carry a reminder time that pings the owner when it's due. You can insert a saved email template into any one-to-one message - merge tags fill in from the record - filter the timeline by Notes, Emails, Calls, Meetings or Tasks, and pin the important stuff to the top. Under the hood, all rich text is scrubbed through an industry-standard sanitizer before it's stored or sent.
