refactor: normalize Arduino firmware naming and update docs/UI references

[Wasif-ZA]

Motivation

• Clean up confusing/misspelled firmware paths (e.g., Audrino/esp32 variants) and make on-disk names reflect device roles.
• Ensure documentation and UI bring-up instructions point to the correct sketch locations so contributors can flash the right firmware.
• Correct misleading file headers in ESP32 sketches so in-file metadata matches the actual filenames.

Description

• Renamed and normalized firmware folders and files under Arduino/ to role-based names such as Arduino/esp32_gateway, Arduino/esp32_gateway_udp_ack, and Arduino/esp32_gateway/udp_forward_only/esp32_gateway and moved previously misspelled Audrino/* files into Arduino/.
• Updated references in docs/ARCHITECTURE.md, README.md, and ui/src/app/page.tsx to use the new Arduino/esp32_gateway* paths.
• Fixed the leading comment lines in Arduino/esp32_week10_code.ino and Arduino/esp32_week_7_code.ino so they state the correct filenames.
• Miscellaneous repo hygiene: added CI (.github/workflows/ci.yml), templates (.github/*_TEMPLATE.md), CODEOWNERS, LICENSE, new docs under docs/, improved ui tooling (ui/eslint.config.mjs, ui/package.json, ui/.prettier*), and added smoke test ui/tests/smoke.test.mjs.

Testing

• Ran cd ui && npm run lint which completed successfully (ESLint ran without failing errors).
• Ran cd ui && npm run test which executed the smoke test in ui/tests/smoke.test.mjs and passed.
• Ran cd ui && npm run build which produced a successful Next.js production build.
