fix(deps): bump fast-uri to 3.1.5 and brace-expansion to 5.0.9 (#2672)

npm audit --audit-level=high fails CI on two new high-severity
advisories:

- fast-uri GHSA-7p8r-x3mc-p8w7 (host confusion via backslash
  authority introducer) — pinned at 3.1.4 via overrides/resolutions;
  bump pins to the patched 3.1.5 (still within ajv's ^3.0.1 range)
- brace-expansion GHSA-rgw5-rvv9-x895 (DoS via unbounded intermediate
  arrays) — in-range lockfile bump 5.0.8 -> 5.0.9 under minimatch

npm audit now reports 0 vulnerabilities. yarn.lock regenerated with
Yarn 4.9.2 to keep resolutions in sync.
