Fixes a few bugs/unintended things on both Zelda and Mewtwo, and slight polish on last Zelda changes.

Zelda

Side Special:

• [$] Dins color gradient of red -> yellow reverted to yellow -> red, size and color adj

Up Special:

• [$] Telecancel effect appears frame 0 (slightly more reactable but not really)

Down Special:

• [*] Attempt? to fix bug where it registers an attack input frame 0 and buffers phantom instantly (idk how to test)
• [*] Movement on 368 adjusted to be less deadly upon trades
• [R] Launch input reverted to vanilla, but after shield cancelling it requires a down special input like any other time you launch Phantom.

Mewtwo

• [$] Fixes angled ftilt graphics being deleted as part of previous consolidation of Sound/Expression scripts.
• [*] Fixes grounded-reappearance momentum bugs by using Zelda's (mostly) vanilla angling logic. Ex holding down doing grounded teleport makes you slide backwards, teleporting forwards has no momentum on reappearance, etc.
