refactor: replace bip39 with @scure/bip39

[myxmaster]

Description

This removes the bip39 dependency. @scure/bip39 is now the sole BIP39 implementation.

Tested:

• triggered swap restore flow with the same rescue key —> xpub identical before and after this change
• verified mnemonicToSeedSync output with a known mnemonic using the Ian Coleman BIP39 tool

Code Review

This pull request migrates the project from bip39 to @scure/bip39 across several files, including LightningAddressStore.ts, SwapStore.ts, and VssAuthUtils.ts. A critical issue was identified in SwapStore.ts where the BIP39_WORD_LIST constant is used but not imported, which will result in a runtime ReferenceError.
