[ci] Remove all actions/cache steps from workflows

This commit removes the entire actions/cache steps (not just .cache
directory) from all workflow files to measure the true performance
impact of caching vs no caching.

Changes:
- ci-lint-format.yaml: Removed tool outputs cache
- ci-tests-storybook.yaml: Removed storybook build cache (both jobs)
- ci-tests-unit.yaml: Removed coverage and vitest cache
- api-update-electron-api-types.yaml: Removed tsbuildinfo cache
- api-update-manager-api-types.yaml: Removed tool cache and repo cache
- api-update-registry-api-types.yaml: Removed tool cache and repo cache
- release-draft-create.yaml: Removed tsbuildinfo cache
- release-pypi-dev.yaml: Removed dist and tsbuildinfo cache

Note: pnpm package caching via setup-node still remains active.
