List of accidential/drive-by improvements against python webapp

[AMDmi3]

No action items, just a list for history. Close when webapp migration from python is complete.

• Badges
  • Badge width is calculated more precisely, as for some reason Rust ttf-parser returns more correct text width that python's PIL.
  • Text vertical alignment is also more correct, as dominant-baseline property was used instead of guessed pixel offsets
• /package/*/information endpoint
  • Version list is sorted consistently with regard to sink flag.
• Internals
  • A few places no longer use sort to get e.g. package with max version
• /tools/project-by endpoint
  • In a case of ambiguity, list of target projects is now sorted, which not only looks better in HTML, but makes autoresolve deterministic and also more likely to choose more suitable target, because the variants usually differ in suffixes (such as yuzu and yuzu-qt5), suffixless variants are likely to more generic and suitable as default, and these are sorted before
  • More error cases are now covered in explanation page (such as missing parameters)
  • Any get parameters are now passed to target page
• Static files
  • URLs which include hashes of file contents are now autogenerated, so we no longer need to bump file versions manually.
• badge/version-only-for-repo legacy endpoint
  • No longer adds header= param to the target url
• Many
  • URLs are now properly escaped in html/xml replies
