feat: Add GitHub Actions workflows for frontend CI/CD (#5)

* feat: Add GitHub Actions workflows for frontend CI/CD

- Add lint.yml: TypeScript and ESLint checks
- Add build.yml: Vite application build pipeline
- Add docker-build.yml: Multi-arch container image builds
- Add deploy.yml: Production deployment to Docker Swarm
- Add dependabot.yml: Automated dependency updates

Follows Single Responsibility Principle with focused workflows.
Includes security best practices, caching, and deployment automation.

* fix: Add missing Dockerfile and lint script for CI/CD workflows

- Add Dockerfile for multi-stage Node.js build with production optimizations
- Add lint script to package.json that runs TypeScript type checking
- Enable health check endpoint in Docker container
- Configure proper user permissions and security practices

Fixes docker-build workflow failures and enables complete CI/CD pipeline.

* fix: Enable Corepack for Yarn 4.x compatibility in Docker build

- Enable Corepack in Dockerfile to support packageManager field
- Fix lint script to use TypeScript checking instead of invalid yarn check
- Remove manual yarn installation from Dockerfile since Corepack handles it

* fix: Enable Corepack in CI workflows to resolve Yarn version conflicts

* chore: Update to latest GitHub Actions versions

- Update actions/checkout to v6
- Update actions/setup-node to v6
- Update actions/upload-artifact to v5
- Update Node.js to version 22 (Active LTS)
- Update Docker base images to node:22-alpine

* Fix Corepack/Yarn caching issue in CI workflows

- Remove cache: yarn from setup-node action to prevent yarn usage before corepack enable
- Enable corepack immediately after Node.js setup
- Add manual yarn caching using actions/cache@v4 with proper cache directory path
- This resolves the packageManager field conflict in CI

* Fix BlogEdit.tsx import and component issues

- Fix import path from @/api/blog-api to @/lib/api/blog-api
- Replace TagManager component with simple tag input since BlogEdit uses plain state
- Remove unused handleTagsChange function
- This resolves the build error where blog-api file was not found

* Fix Yarn 4.x deprecated commands in Dockerfile

- Replace --frozen-lockfile with --immutable in builder stage
- Replace --frozen-lockfile --production with --immutable + autoclean in production stage
- This resolves the Yarn 4.9.0 deprecation warnings and build failures

* fix: optimize Dockerfile to use Yarn PnP instead of node-modules

- Use Yarn Plug'n'Play (PnP) for faster installs and smaller image size
- Keep .yarnrc.yml configuration instead of overriding it
- Copy PnP files (.pnp.cjs, .pnp.loader.mjs, .yarn cache) to production stage
- Use yarn workspaces focus --production for production dependencies
- Corepack manages Yarn version while PnP handles dependency resolution

* fix: correct CI/CD workflow issues

- Fix lint.yml to use 'yarn check' instead of 'yarn lint' (ESLint not configured)
- Fix Dockerfile to use 'yarn install --production' for single package repo
- Update workflow name to reflect actual functionality
