docs: fix bd daemon CLI syntax to use flag format (#568)

The bd daemon command only accepts flags with '--' prefix, not subcommands.
Fixed all documentation to use correct syntax:

- bd daemon start -> bd daemon --start
- bd daemon status -> bd daemon --status
- bd daemon stop -> bd daemon --stop
- bd daemon restart -> bd daemon --stop && bd daemon --start
