Fix: ledger no request keys context

[edgarkhanzadian]

Try out this version of Leather — Extension build, Test report

• Fixes Signing in with hardware wallet sometimes results in "No LedgerRequestKeysContext found" if bitcoin app is on instead of stacks #4682 and Ledger "unexpected application error!" after clicking the account to connect with "No LedgerRequestKeysContext found" #4786 by using location state for chain name in ledger connect error, as it sometimes doesn't have access to LedgerRequestKeysContext
• Fixes Refactor repeating signing code into generic hook #4863, refactored a good chunk of code into useLedgerSignTx hook and TxSigningFlow provider.

Here's some testing of different scenarios:
