[Bug] Journey Editor: Sticky note missing markup support + Run button blocked after saving as draft

[IamKirbki]

Bug 1: Sticky notes don't support markup or newlines

Sticky notes in the journey editor render plain text only, no markup support, and newlines are completely ignored. What you type is not what you get.

Expected behavior:

• Newlines should be respected and rendered as line breaks
• Basic markup (bold, italic, etc.) should be supported, or at minimum newlines

Actual behavior:

• Newlines are stripped/ignored
• No formatting is rendered

Bug 2: Run button stays blocked after saving journey as draft

After saving a journey as a draft, the Run button remains disabled/blocked. The only way to get it back is to do a full page reload.

Expected behavior:

• Run button should become available immediately after saving as draft, without requiring a page reload

Actual behavior:

• Run button stays blocked post-save
• Page reload required to re-enable it

---

Steps to reproduce (Bug 2)

1. Open a journey in the editor
2. Save it as a draft
3. Attempt to click Run
4. Observe that the button isn't functional
5. Reload the page -> button is now functional
