Local Dev c1988b9674 fix(aegis): DigiByte import failed on every OTA install
Reported as "the Aegis DigiByte import error". The vendored @dgb-wallet/core
modules under lib/dgb/ imported "bitcoinjs-lib", "bip32", "ecpair",
"bip39" and "@bitcoinerlab/secp256k1" as bare specifiers. Node's ESM resolver
walks up from the importing file, so that resolves in a dev checkout — where
Theseus's node_modules sits above the add-on — and resolves nowhere once
Aegis is running from <userData>/extensions/aegis/, which is every OTA
install. The import threw, index.js caught it and set dgbCore = null, and any
DigiByte import then died in digibyteNetwork() with "DGB adapter not
available".

So DigiByte worked on a fresh install and disappeared after the first update.
Confirmed on this machine: the only node_modules reachable from the installed
extension carries bip39 and none of the other four.

lib/dgb/deps.js now holds the dependencies, injected by index.js from
api.require (which resolves against the app tree) before anything under
lib/dgb/ is imported — the same pattern every other lib/*.js in Aegis already
uses, and the reason that pattern exists. Consumers read them through
accessors rather than capturing them at module scope, so import order is no
longer load-bearing: hd.js builds its bip32 on first use and the two
initEccLib callers go through a once-only ensureEcc(). Using a DGB module
without injection now throws a named error instead of a resolver failure
swallowed into a null.

Verified by loading the modules from a directory with no reachable
node_modules and deriving real addresses: BIP44 D…, BIP49 S… with its legacy
3… pair, BIP84 dgb1q…, BIP86 dgb1p… taproot, plus a WIF round-trip and the
non-DGB WIF rejection.
