Fixes ethernet initialisation of static IP settings and modified some debug info

[brettbear]

Summary
#5247

The static IP configuration happened too late in the ethernet initialization sequence.
The ETH.config() call from the event handler was moved to just after ETH.begin().

Additionally, initEthernet() was called before config deserialization was complete.
The initEthernet() was moved later in the config deserialization to ensure static IP and DNS configuration is completed prior to ethernet initialisation.

Testing performed
Build with default_envs = esp32_eth (no platformio_override.ini used)
WiFi Setup already exists (AP SSID customised, static IP set with custom DNS server address and AP opens set to 'No Connection after boot')

Tests done with and without DHCP being enabled on the Ethernet network. Expected behaviour seen regardless of DHCP or static IP Address usage.

Walkthrough

Reorganizes Ethernet configuration parsing in cfg.cpp by relocating the Ethernet deserialization block within deserializeConfig, and refactors Ethernet initialization logic in network.cpp by moving static IP configuration from the ETH_CONNECTED event handler to the post-ETH.begin phase and updating related logging messages.

Changes

Cohort / File(s)	Change Summary
Configuration parsing reordering wled00/cfg.cpp	Ethernet configuration block moved from pre-id position to post-DNS, pre-ap position within deserializeConfig; behavior unchanged with issue reference comment added.
Ethernet initialization and static IP configuration wled00/network.cpp	Log messages updated from "initC" to "initE"; static IP configuration logic relocated from WiFiEvent (ETH_CONNECTED) to immediate post-ETH.begin with conditional application based on multiWiFi[0] settings; ETH.config call removed from event handler.

thanks, looks good to me (I can't test as I have no such hardware)

[brettbear]

Cool - do I need to do anything else or are we good @DedeHai?

[DedeHai]

all good, just waiting for some more feedback

[brettbear]

@DedeHai & @softhack007 - sorry to nag, but can this BR be reviewed and approved?

[softhack007]

also I don't have any ethernet board to test with.
Code changes look ok for me, the PR seems to just move some code block around,

[DedeHai]

@softhack007 we can just "release into the wild" and see if there is any negative feedback.

[brettbear]

Correct... just moving code blocks around. It had no right to work before and it didn't. I'd be surprised if the changes break anything else.
