zhangwenjian a43133ab7b fix🐛: stop demo mode serving the writes that are registered as GET
DemoEvn decided by HTTP method: GET and OPTIONS through, everything else
refused. Three of the code generator's routes are registered as GET and write
anyway - two emit Go source files onto the server's filesystem, and the third
inserts menus, APIs and casbin rules into the database. They sit in a group
whose own name says it does no role check, and a demo deployment lets anybody
log in. So on the demo host any visitor could write to the machine and to the
database, and the one that writes menus had in fact been used: three generated
SysCasbinRule entries is how this was noticed.

The guard now also looks at the matched route. The method cannot answer the
question - whether a request changes anything is not something the verb reports
truthfully here - so the three are named, as gin route patterns, which is what
Context.FullPath returns and how CasbinExclude already spells them.

Changing them to POST would be the better shape and is not this change. sys_api
records an endpoint by method and path and the casbin policy follows it, so
flipping the verb needs a migration and a policy resync; until both land, every
existing deployment would start answering 403 to a role that could use the
generator the day before.

The read-only half stays reachable: preview, the table tree, and the two
database listings. A demo host that cannot demonstrate the generator is as
broken as one that lets visitors write to it - refusing too much is the same
defect facing the other way, and there is a test for that direction too.

Half of the general hole is closed and the other half is written down. The
closed half is a test beside the route registrations: it builds the generator's
routes, enumerates them, and fails if any entry in the guard has stopped being
a real route, so renaming one turns the list red instead of quietly making it
match nothing. It lives there because common/ may not import app/ - which is
also why the guard cannot check its own list from where it is. The open half is
that no static check can tell a handler that writes from one that reads, so the
next GET that writes has to be added by hand. The comment says that rather than
leaving the impression the class is covered.

application.demomsg was configuration nothing read. The message was hard-coded
in the middleware, and the demo host's configured string happened to be
identical, so the setting looked like it worked and never had. It is read now,
with the old string kept verbatim as the fallback, so a deployment that never
set it is answered exactly as before.

This covers demo mode only. On a deployment that is not a demo those three
routes remain in CasbinExclude and stay reachable by any authenticated user
whatever their role; that is a separate decision and is not touched here.
