Remediation recommended

1. Upgrades leave pan and tilt reversed 🐞 Bug ≡ Correctness

customizer.sh writes the corrected ptz_gpio value with fw_setenv, but the customizer does not
rerun when an existing installation upgrades. Those cameras retain the previous mapping in their
preserved bootloader environment, so the direction fix reaches fresh installations but not ordinary
upgrades.
Agent Prompt 
## Issue description
Existing installations preserve the old `ptz_gpio` environment value during upgrades, so changing the first-boot customizer alone does not correct their pan/tilt direction.

## Fix Focus Areas
- devices/gk7202v300_lite_xm-rm1/general/overlay/usr/share/openipc/customizer.sh[20-25]

## Recommended Fix
Add an upgrade-time or boot-time migration that replaces the previous `ptz_gpio` value with the corrected value. Match the old value before changing it so user-customized mappings remain intact.
