v0.1.2 — Copy fix, BMC, icons

Fixes

• Copy button now works behind HA Ingress (HTTP). navigator.clipboard is undefined in non-secure contexts; fallback uses execCommand('copy').
• Added a copy button for the private key as well.

New

• Buy Me a Coffee button in the UI footer and in both READMEs
• icon.png and logo.png for the HA add-on store
• LICENSE (MIT)
• GitHub FUNDING.yml for the Sponsor button
• Rewritten root README with badges and one-click "Add to HA" link

Notes

.onion URLs still require the Tor Browser — Chrome/Firefox cannot resolve them.
