build(deps): upgrade chokidar, pinia, and jsdom majors and drop unused deps

Move chokidar to 5, pinia to 4, and jsdom to 30 with a matching
@types/jsdom, and align packages/types on TypeScript 6 with the other
workspaces.

chokidar 5 is ESM-only while the server compiles to CommonJS. Node's
require(ESM) support covers this, verified against a live watcher and a
nest watch build rather than the mocked unit tests.

Remove @fastify/formbody and @tanstack/vue-table, neither of which had a
single caller, along with the stale @tanstack/vue-table entry in the Vite
optimizeDeps list.

Hold TypeScript at 6. typescript-eslint refuses to install alongside 7 and
vue-tsc cannot drive the native checker until the stable compiler API
lands in 7.1.

Ignore pnpm-lock.yaml in prettier so lint-staged stops rewriting it out of
pnpm's native style, which was inflating every lockfile diff to roughly
19k lines.
