fix(fedimint): gateway/guardian follow the running bitcoin container via {{BITCOIN_HOST}}

Browse Source 
The gateway crash-looped dialing bitcoind at host.archipelago:8332 (the
host gateway IP, where bitcoind does not listen). Root-cause fix, three
parts:

- fedimint-gateway manifest: --bitcoind-url now comes from
  $FM_BITCOIND_URL, filled by a {{BITCOIN_HOST}} derived-env — works on
  Knots, Core, or any future Bitcoin distro.
- fedimint manifest: same derived-env replaces the hardcoded
  FM_BITCOIND_URL=http://bitcoin-knots:8332 environment entry.
- orchestrator: removed the hardcoded FM_BITCOIND_URL=bitcoin-knots
  override that clobbered the derived-env, and bitcoin_host() now
  accepts any running bitcoin*/bitcoin container (excluding -ui and
  archy-* sidecars), preferring the known names in order.

Catalog regenerated + signed (nodes install from the signed catalog, so
the manifest fixes only reach them via this regen).

# The bitcoind host comes from $FM_BITCOIND_URL, filled by the
# {{BITCOIN_HOST}} derived-env below — it resolves to whichever bitcoin
# container is actually running (Knots, Core, or any future distro archy
# ships), so the gateway is never pinned to one node's container name.
# (Was hardcoded http://host.archipelago:8332 — the host gateway IP where
# bitcoind does not listen — which crash-looped the gateway, 2026-07-22.)
