fix(v2)(ui): finish expanding self-closing q-* tags (rules-attribute corner case)

The earlier mass rewrite in cb19ba3 used a regex with `[^>]*?` to match
attribute spans, which stops at the first `>` it encounters. That broke
on tags with `:rules="[v => ...]"` where the JS arrow function's `>`
character truncated the match short of the actual `/>`. 8 tags survived
the rewrite (mostly form fields in dialog bodies). The Add-machine
dialog was the most visible victim — Vue's compiler tried to make
sense of the partially-malformed q-input and dumped the machine_npub
field plus the next two siblings side-by-side instead of stacked.

Fix: replaced the regex pass with a small stateful scanner that walks
the file tag-by-tag and is quote-aware (treats `>` inside paired
double or single quotes as literal characters, not tag terminators).
The scanner found and expanded the remaining 8 tags + verified zero
self-closing q-* tags remain anywhere in the template. 343 q-* opens
total in the file.

Caught while clicking through the Add-machine dialog in the UI.
