No you can't.

You are confusing concepts. dnsmasq.conf does not forward URLs, and
works at a lower level.  When browsers come into play, dnsmasq only ever
sees the host name.  The rest of the URL or URI is a matter between
browser and web server at a much later stage, and dnsmasq isn't ever
aware of it.

Instead, if the forwarded query gets replied to with "no such domain",
only then will dnsmasq resolve to 192.168.1.1.

Note you need server directives if using address=/#/anything - check the
dnsmasq manual.

If you want specific URL rewriting, you need to set up and configure a
web server to do that, and to transparently proxy the remaining
requests, which may require network-level traffic redirections through
PF or netfilter.

This is a complex matter and requires a level of network expertise for
several components that you don't appear to have, hence the "no".
