fix: resolve plugin path relative to binary location + copy plugins in build

- main.go: use filepath.Dir(os.Args[0]) instead of ./plugins for discovery
- api/app.go: same fix for ReloadPlugins
- build.sh: copy plugins/ to build/bin/plugins/ after wails build
- Fixes: plugin not found when binary launched from different CWD
