feat(reset): drive and verify on-device dice-entropy collection

Regenerated bindings for device-protocol feat/dice-entropy
(ResetDevice.dice_entropy, DebugLinkDecision.input,
DebugLinkState.dice_digest, ButtonRequest_DiceRoll). debuglink gains
press_input() (chunked synthetic roll injection; each chunk must fit
the firmware's 40-char max_size) and read_dice_digest().

test_reset_device_dice runs the full flow against the emulator: the
DiceRoll ButtonRequest announcement, injection in 40-char chunks with
undo churn, a host-side simulation of the same append/undo rules, the
device digest matching sha256 of exactly the expected 99-roll string,
and the post-mix internal entropy still producing the documented
sha256(internal || external) mnemonic. Version-gated to 7.15.0.
