fix(java): repair Java debugger configuration and add run keymaps

- Fix debug bundles not being passed to JDTLS init_options
- Add on_attach callback to setup DAP after LSP attaches
- Remove broken manual Java DAP adapter (now handled by nvim-jdtls)
- Add java-debug-adapter and java-test to Mason ensure_installed
- Add new Java keymaps: debug, test, run (file/maven/gradle)
