v2.6.1 — Retryable TV authorization

Retryable TV authorization

Denying the pairing dialog on the TV used to leave a broken key file behind, and since v2.6 preserves the key across reinstalls, recovering required a manual uninstall/install. Pairing is now a verify loop in a standalone script:

sudo /opt/lgpowercontrol/authorize.sh

A valid key passes silently; a missing or broken key triggers a fresh dialog on the TV until it is accepted. The installer runs the same script as its final step, and it is installed next to update.sh — so re-pairing after a TV factory reset needs no repo checkout.

This is also the first release installable via the built-in updater: sudo /opt/lgpowercontrol/update.sh
