v1.3.3 — editor modal fills full webview height

Fixed

• Editor modal now fills the full webview height. Previously the New / Edit note dialog was vertically centered inside the backdrop and capped at max-height: 92vh, which made it look like a half-height popup when the library was opened in a narrow panel (e.g. the secondary sidebar). Backdrop now uses align-items: stretch, the modal takes height: 100% of the available area, and the body textarea / Markdown preview flex-grow to fill remaining space inside the modal. Min-heights for textarea and preview reduced from 220 px to 120 px so the modal still renders correctly in very short panels.
