build(makefile): simplify build system by removing unused tooling

- Simplify the build process by removing the generate step dependency from build, test, and Linux build targets
- Remove templ-related tooling, variables, and targets, including installation, generation, watch mode, and cleanup of generated files
- Remove hot reload support via air and its associated dev targets
- Drop Docker build and run targets from the Makefile
- Clean up unused PHONY declarations and related tool checks
