fix(deps): upgrade packages and add resolutions for picomatch and brce-expansion

[ilayda-cp]

Done

Upgraded @percy/cli, @typescript-eslint/eslint-plugin, @typescript-eslint/parser, @vitest/ui, and stylelint to their latest versions.

Added picomatch >=2.3.2 and brace-expansion >=2.0.2 resolutions to fix transitive vulnerabilities that couldn't be resolved by upgrading direct dependencies. Reduced audit findings from 48 to 1 (remaining is a low-severity test-only dep in @canonical/store-components).
