Task #25: Provision LNbits on Hermes VPS for real Lightning payments.
Changes:
- dev.ts: /dev/stub/pay/:hash now works in both stub and real LNbits modes.
In real mode, looks up BOLT11 from invoices/sessions/bootstrapJobs tables
then calls lnbitsService.payInvoice() (FakeWallet accepts it).
- sessions.ts: Remove all stubMode conditionals on paymentHash — always expose
paymentHash in invoice, pendingTopup, and 409-conflict responses.
- jobs.ts: Remove stubMode conditionals on paymentHash in create, GET awaiting_eval,
and GET awaiting_work responses.
- bootstrap.ts: Remove stubMode conditionals on paymentHash in POST create and
GET poll responses. Simplify message field (no longer mode-conditional).
- Hermes VPS: Funded LNbits wallet with 1B sats via DB credit so payInvoice
calls succeed (FakeWallet checks wallet balance before routing).
Result: 29/29 testkit PASS in real LNbits mode (LNBITS_URL + LNBITS_API_KEY set).
