Subject: [PATCH] fix: place cursor at beginning of text field when quoting a
 note

When a user hits Quote, the new post screen opens with the nostr URI
pre-filled but the cursor was at the end (after the URI). This moves
the cursor to the beginning so the user can immediately start typing
their commentary.
