Remove EEPROM support

[DedeHai]

removing all references to eeprom since this has been deprecated for a long time.

Summary by CodeRabbit

• Refactor
  • Removed legacy EEPROM storage support throughout the application, consolidating configuration management to filesystem-only operation.
  • Simplified factory reset process to clear only filesystem settings and reboot; EEPROM clearing step has been eliminated.
  • Removed EEPROM fallback path for configuration loading, ensuring settings are exclusively managed through filesystem storage.

Walkthrough

This pull request removes legacy EEPROM support infrastructure from WLED. Changes include deleting the entire EEPROM implementation file, removing EEPROM-related function declarations, eliminating EEPROM fallback paths in configuration deserialization, and simplifying factory reset and initialization flows to omit EEPROM clearing operations.

Changes

Cohort / File(s)	Summary
Factory Reset Paths wled00/button.cpp, wled00/set.cpp	Removed EEPROM clearing step from button-0 factory reset and RS (security) factory reset paths. Filesystem formatting and reboot remain; conditional EEPROM clear is omitted.
Configuration Deserialization wled00/cfg.cpp	Removed fallback EEPROM read path in deserializeConfigFromFS. Config filesystem failure no longer triggers EEPROM load attempt via deEEPSettings().
Public Declarations and Headers wled00/fcn_declare.h, wled00/wled.h	Removed EEPROM-related public function declarations (applyMacro, deEEP, deEEPSettings, clearEEPROM) and removed EEPROM.h include statement.
Boot-Time Initialization wled00/wled.cpp	Replaced conditional EEPROM handling with unconditional initPresetsFile() call. Removed deEEP() invocation and collapsing of #ifdef branches.
Legacy EEPROM Implementation wled00/wled_eeprom.cpp	Entire file deleted. Removed EEPROM versioning constants, settings load/migration functions (loadSettingsFromEEPROM, deEEP, deEEPSettings), factory reset (clearEEPROM), version-conditional migration logic, and subsystem-specific EEPROM state handling (DMX, HueSync, ABL, MQTT, timers, presets).

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~50 minutes

• Cross-file consistency: Verify all EEPROM call removal sites are consistent and no orphaned references remain.
• Factory reset verification: Confirm that both button-0 and RS reset paths maintain correct behavior without EEPROM clearing.
• Config fallback logic: Ensure deserializeConfigFromFS failure handling is appropriate without EEPROM fallback.
• Initialization correctness: Validate that initPresetsFile() properly replaces removed deEEP() call in boot flow.
• Deleted file impact: Review that removal of extensive EEPROM migration and versioning logic does not affect existing configurations or user experience.
