chore(deps): clean up redundant pnpm overrides

Remove 8 overrides that are no longer needed because parent semver
ranges now resolve to safe versions naturally. Update undici pin
from 6.24.0 to 6.24.1.

Removed overrides (redundant):
- lodash@<=4.17.22 -> 4.17.23
- dompurify@<=3.3.1 -> 3.3.2
- fast-xml-parser@<5.5.7 -> 5.5.7
- picomatch@>=4.0.0 <4.0.4 -> 4.0.4
- yaml@<1.10.3 -> 1.10.3
- handlebars@>=4.0.0 <4.7.9 -> 4.7.9
- brace-expansion@<2.0.3 -> 2.0.3
- brace-expansion@>=4.0.0 <5.0.5 -> 5.0.5

Retained overrides (still active):
- minimatch@<3.1.4 -> 3.1.4
- rollup@<2.80.0 -> 2.80.0
- undici@<6.24.1 -> 6.24.1 (bumped from 6.24.0)
