update dependency eslint and unblock frontend deps upgrades

[jonnalley]

What changed

Upgrades eslint from 10.2.1 to 10.3.0 (minor version bump) and regenerates frontend/bun.lock to match.

This replaces Renovate PR #5625, which failed CI because Renovate could not update the bun lockfile (artifact failure). The --frozen-lockfile check in CI rejected the stale lockfile, cascading into failures across all frontend CI jobs.

frontend/package.json — bumped eslint version from 10.2.1 to 10.3.0

frontend/bun.lock — regenerated to reflect the new eslint version and integrity hash

Issue

Replaces #5625 (Renovate PR with artifact failure)

How to test

1. Verify CI passes — all frontend jobs (Linting, Frontend Unit Tests, Storybook Build, A11y Regression Gate, E2E tests) should succeed now that the lockfile is in sync
2. Locally:

   cd frontend
   bun install --frozen-lockfile  # Should succeed without errors
   bun run lint                   # Should work with eslint 10.3.0
