enhancement: Adds IntelliTect celebration pattern

[mszym99]

Wokwi Link

Introduces a new IntelliTectPattern for celebration displays. This pattern features expanding rings of IntelliTect blue, white, and black emanating from the center of the LED strips. After the rings fully expand, the pattern transitions to a sustained pulse of solid IntelliTect blue across all strips.

Example video shows full run along with consecutive successful hit resets:

Scope the switch cases to keep the sketch buildable

When the ESP8266 sketch is compiled as C++, this case 1 label jumps past the initialized center and ringWidth variables declared under case 0, which GCC rejects with “jump to case label crosses initialization.” Enclose each case body in braces (as the earlier implementation did) or move those declarations outside the switch; otherwise the firmware cannot be built.
