build(deps-dev): move the whole stylelint family to 17 as one upgrade

stylelint 15.11.0 -> 17.14.1 with every package that peers on it:

  @nextcloud/stylelint-config           ^2.4.0  -> ^3.2.2
  stylelint-config-recommended-scss    ^13.1.0  -> ^17.0.1
  stylelint-config-recommended-vue      ^1.6.1  -> ^2.0.0
  postcss-html                          ^1.8.1  -> ^2.0.0
  stylelint-config-html                (absent) -> ^2.0.0

None can move alone: vue-config@2 peers 'postcss-html ^2.0.0' and
'stylelint-config-html >=2.0.0'; postcss-html@2 breaks vue-config@1.6.1's own
'^1.0.0' peer; scss-config@17 peers 'stylelint ^17'. @nextcloud/stylelint-config
is the member that decides it — v2.4.0 still declares indentation /
string-quotes / number-leading-zero / selector-list-comma-newline-after, all
removed in stylelint 16.

Then 10 real errors, in 4 files:
  8x  word-break: break-word  -> overflow-wrap: break-word
  1x  word-wrap: break-word   -> overflow-wrap: break-word
  1x  clip: rect(0,0,0,0)     -> clip-path: inset(50%)

Fixed by hand, NOT with --fix. The autofix also rewrites the 86 advisory
csstools/use-logical warnings (text-align: left -> start, padding-left ->
padding-inline-start, ...) across 28 files. Those change how the UI lays out
under RTL and have nothing to do with this bump; openbuild, scholiq and hermiq
all carry the same warnings unfixed. A dependency upgrade should not smuggle in
a directional-CSS change.

Result: 10 errors -> 0, exit 0. The 86 warnings are unchanged and non-blocking.
