Replace seed gift links with presigned PSBT claim links

Gifting no longer shares a seed. "Gift some Bitcoin" (Settings) presigns
a chosen amount as a #gift= link: one SIGHASH_SINGLE input (the sender's
change output is cryptographically fixed, so a front-runner can only take
the gift portion, never the change) plus the rest left open. The coin is
reserved per-wallet so normal sends skip it; reclaim it anytime.

Opening the link generates a brand-new wallet the sender never sees,
shows the amount, and on Claim adds the claimer's address as the output,
finalizes, and broadcasts — then prompts backup of the fresh seed. This
gives forward secrecy (sender locked out once confirmed), one-shot
semantics (claiming spends the input), and keeps funds in the sender's
wallet until claimed.

Crypto verified end-to-end (sign NONE/SINGLE -> add output -> finalize ->
valid tx; deterministic-signature equality proves the presigned sig is
valid for any output the claimer picks). Strings retranslated across all
19 locales.
