feat(ecash): import a backup phrase from another NUT-13 wallet
Bring-your-own, the open question the migration plan left. Point this
wallet at a phrase you already hold — Minibits, Nutstash, cdk-cli — and
its coins become restorable here, which is the other half of "these
words are portable".

Replacing an established phrase is the one genuinely lossy thing this
module can do, so it is treated that way. The coins already held stay
spendable: they are proofs, not derivations, and nothing here touches
`ecash.json`. But they were minted under the *old* phrase, so a restore
will no longer find them. Hence an explicit confirm, a prompt to reveal
and write down the current phrase first, and — most importantly — the
replaced phrase is archived beside the wallet, never overwritten. It may
be the last copy of the words a balance was minted under, and quietly
destroying that is precisely what this module exists to prevent.

Re-importing the phrase already in use is a no-op rather than a
replacement, so it archives nothing.

Counters are deliberately left alone. They are per-keyset and
seed-relative, so under a new seed they merely start high, which costs
nothing because a restore scans from zero regardless. Resetting them
would be the dangerous choice on the day someone imports the phrase they
were already using.

`imported` is its own provenance rather than reusing `independent`: both
mean the node's recovery phrase does not cover the wallet, but only one
of them means the operator already knows where else the words live.

15 NUT-13 tests green, 1000 frontend tests green.

// NUT-13 mints coins that no phrase can bring back — and the card says so
// rather than implying a backup already exists.
// 2. These are standard BIP-39 words for a NUT-13 wallet, so they restore in
// Minibits, Nutstash or cdk-cli. Hence `SeedRevealPanel` without `aezeed`:
// the SeedQR tab is genuinely useful here.
