improve font situation

[schlawg]

firefox 134 no longer likes the installed Noto Sans on fedora linux. it renders in italics. so fix that again, but really this time, and make some other improvements.

• replace our noto sans and roboto woff2s with variable versions so we can render any weight from 100 to 900.
• add a replace function to client build asset hashing - provide a filename along with a glob and it will update any globbed paths inside that file to the hashed urls
• use that replace function to make a new font-face.css with correct asset urls, fixing the issue where some fonts preloaded by layout.scala were duplicated and ignored
• minor font-weight edits in css because our Roboto is no longer Light.
• remove local: 'Noto Sans'/'Roboto' rules from our @font-face blocks because we don't care about your shitty installed fonts. we only show the new hotness now.

this common/package.json bit triggers the font-face.css substitution:
