ST25 dynamic NFC tag: EEPROM wearing problems

[araobp]

The signage app needs some improvements to avoid the EEPROM wearing problems.

Currently, new URL is written on EEPROM every 10 seconds.

Improvements:

• Write a base URL onto EEPROM for the first time.
• webapp.js updates "ref" as a variable on STM32's SRAM, when a new POST request has been received from the signage SPA.
• When the firmware on STM32 has detected GPO interrupt (RF Field Change event), the firmware writes a new URL onto EEPROM, and "ref" is appended to the base URL like "&ref=something".

The problem is that I have nearly lost my development environment since last week. Unfortunately, CubeIDE is very unstable, and my DELL PC is broken (its quality is no good)...
