bitcoin-wallet, extracted into plugins/bitcoin-wallet — the platform half

Tenth extraction, and the first where the blocker was a permission rather than
a path. The wallet was kind: 'admin' — owner only, never grantable — and plugin
permissions are always kind: 'app'. mount.ts forces that and the manifest has
no field for anything else, deliberately, so a plugin cannot ask to be
restricted. Extraction therefore could not preserve admin.

Raised before moving any code, because turning "the server owner's bitcoin"
into a row in the grants list beside Photos and Music is the kind of change
nobody notices until someone ticks it.

Made anyway, and the objection inverts: every wallet query is scoped by
user_id, taken from X-Officer-User which the platform injects from the session,
so granting the permission gives an account its OWN wallet rather than access
to anyone else's — including to the owner, whose bypass covers permission
checks and not query scoping. kind: 'admin' was single-user thinking.

Named bitcoin-wallet, not wallet: appName drives route, API prefix, table
prefix and install key together, so the name should say what it is. Tables are
bitcoin_wallet_*; the prefix guard normalises the hyphen. Verified free before
committing to it — no wallet table exists on any server, and db:push would
treat a rename as a drop plus a create.

registry.test.ts re-anchored: `wallet` was its canonical kind: 'admin' fixture
and its no-selfService fixture. Now user-admin/server-admin and terminal, with
a note that a plugin's permissions are always `app` — which is exactly why this
one needed a decision rather than a default.
