Stage D batch 6: mama_forth_words.c group 4 -- identity/crypto words (FABRIC-3.md §XXXII.6)

MINT + mint_pop_string()/ZUSE-ELIGIBILITY-ADD/ZUSE-ELIGIBLE?/
ELEVATE-PUBKEY-UNPACK, 10 sites. mint_pop_string() gained a field_name
parameter so its diagnostics name which of MINT's four string
arguments failed (phone/email/username/full_name), rather than a
generic message that would leave the operator guessing. Diagnostic
placement matched each function's own sibling convention where one
exists (ZUSE-ELIGIBILITY-ADD), log_message() default otherwise.

Three-arch clean qemu acceptance passed.
