Bug 1: GreenPrintln called with format args (wrong function)

File: rocketpool-cli/claims/claim-all.go, line ~322

// Old
fmt.Printf("  %sSuccessfully distributed balance of minipool %s.%s\n", colorGreen, mp.Address.Hex(), colorReset)

// New (BUG)
color.GreenPrintln("Successfully distributed balance of minipool %s.", mp.Address.Hex())

GreenPrintln takes ...string — it doesn't accept format specifiers. The %s will be printed literally, and mp.Address.Hex() will be ignored entirely. Should be color.GreenPrintf(...).

Bug 2: GreenSprintf result is discarded (silent no-op)

File: rocketpool-cli/service/service.go, printPatchNotes function

// Old
fmt.Printf("%s=== Smart Node v%s ===%s\n", colorGreen, shared.RocketPoolVersion(), colorReset)

// New (BUG)
color.GreenSprintf("=== Smart Node v%s ===\n", shared.RocketPoolVersion())

GreenSprintf returns a string — it doesn't print anything. The version header is silently dropped and never displayed.
