fix(notes): a [[note]] link is one you can follow

Picking a note from the [[ completion wrote [[Title]] and the server made a real
link from it — but the link only ever showed in the panel under the note as plain
text. It said the note pointed somewhere and gave no way to go there, which reads
as "it didn't become a link at all".

The links in that panel are buttons now. A [[note]] resolves by its title to the
note — the one already on the list, or looked up if not — and opens it in place; a
#project goes to its page; a task link to the task. Titles with punctuation work,
brackets and parentheses included, because the match is on the whole title, not a
parse of it.

e2e: after linking a note, clicking its chip opens the note it names.
