refactor(corpus): deshadow ouais_je_funk too — PLN's call, he takes it from there

Held out of daf074f2 because the file was already in PLN's modified set and the
standing rule is not to commit over his uncommitted .tidal work. He waived it:
"commit over ouais je funk do the fix there too ill take it from there."

Same mechanical change as the other 254 files — the 7-line shadow stanza removed
so BootTidal.hs is the only definition:

    let gMask  = (midiOn "^41" (mask "t!3 <t!3 [f <t f>]>"))
    let gMute  = (midiOn "^73" (mask "f*16"))
    let gMute2 / gMute3
    let gM1 = gMask . gMute   /  gM2  /  gM3

`let width` and `let dMask` are untouched: BootTidal defines neither, and dMask
is this track's own compositional mask, not boilerplate.
