Thread the remaining allowance through every spend path (pay_invoice, pay,
pay_keysend, internal transfer) as maxTotal, and have debit() assert the spend
stays within it after it reloads the invoice and captures the tip — so a
delegated NWC credential can no longer exceed its configured budget, and a
mutated tip can't slip a small-budget check and drain via the internal path.
checkBudget now returns the remaining allowance alongside any error; a blank
budget is treated as deliberately unlimited and a positive budget requires a
known renewal period.
Add operator-controlled containment for a suspected credential disclosure, all
gated behind Redis flags with no hardcoded scope:
nwc:disabled fail every method closed
nwc:credential-cutoff retire connections created before an epoch
nwc:quarantined block an individual disclosed connection
nwc:guard:dormant-keysend quarantine the first keysend on a long-idle app
Fix an ownership check that read the bare pubkey instead of app:<pubkey>, which
let an authenticated user overwrite another connection's config, and validate
budget/fee/renewal inputs.
