More reliable Notion importing and editing

Import and edit Notion posts with safer saves, smoother editor switching, and a layout that adapts when the editing area gets narrow.

We strengthened the full Notion workflow, from importing a page to editing its post settings and switching editor modes.

Imports finish more reliably: a successful Notion fetch now waits for the current editing session when necessary and saves through the supported post workflow.
Post settings have a safer save path: title, description, SEO fields, and images are saved together, with a recoverable copy kept on the device if a save is interrupted.
Editor switching is smoother: inblog waits for active edits to finish before switching and no longer shows a connection error for a normal transition.
The import form fits narrower spaces: the Notion URL field shrinks with the editor instead of sliding under the import button.
