Encapsulate e131.cpp's own runtime state as static, not global

[netmindz]

Summary

Part of an ongoing pass identifying WLED_GLOBAL declarations that are actually only referenced in one file (see #5777-#5781 for earlier ones). 3 more turned out to be private to e131.cpp: highPriority, e131LastSequenceNumber, pollReplyCount.

Converted all 3 to file-local static, using direct constructor syntax for the E131Priority object — equivalent to what WLED_GLOBAL E131Priority highPriority _INIT(3); expanded to when wled.cpp was the definition translation unit.

No behavior change — purely a storage-class change.

Test plan

• esp32dev: builds and links cleanly via pio run -e esp32dev — 1,320,307 bytes flash, no warnings.
• Confirmed via repo-wide grep (wled00/, usermods/) that none of the 3 converted variables are referenced outside e131.cpp.

Walkthrough

The PR moves E1.31 priority tracking, per-universe sequence tracking, and Art-Net poll-reply counting from shared global declarations into file-private state in e131.cpp.

Changes

E1.31 state encapsulation

Layer / File(s)	Summary
Private E1.31 runtime state wled00/wled.h, wled00/e131.cpp	wled.h removes the shared declarations. e131.cpp defines the E1.31 priority, sequence-tracking, and Art-Net poll-reply state locally.
