The Debug button on a Sieve script sent a copy to an outside site, whose
interpreter knows only upstream's extension names: a script that requires
vnd.inbuxa.expressions or vnd.inbuxa.while failed to compile there, and
the button took admins to another project's site.
The playground now ships inside the console and runs the server's own
interpreter. sieve-playground/ is built by inbuxa-server's
tools/sieve-playground (SOURCE.md names the commit); sieve-playground.ts
copies it, with Monaco 0.52.2 from node_modules, into
sieve-playground/<content hash>/ (the server caches every file but the
console's index.html for good) and gives the console its path. The
script stays on the console's origin, so the warning dialog before
opening it is gone.
Strings (en.json): sievepad.failed reworded, sievepad.debugHint added,
the three warning-dialog strings removed.
webui.zip grows from 1.3 MB to 3.4 MB: 0.9 MB of compressed WebAssembly,
the rest Monaco's editor core.
