You said you charged the battery but that doesn't mean anything. We don't know what you did to charge it. what you used, what the battery voltage was when you started and then finished, what is was 6-12 hours later. You every easily could have a dead battery.

Could you measure the battery voltage at the terminals at rest with everything off, and then when you go to start it, and let us know what they read. If you don't have a voltmeter or multimeter, then go buy one for as little as $4-5 because you will always use it.
The headlight and horn may work but the voltage may be too low to turn over the starter.
Do you hear the starter solenoid clicking or any noise when you go to start the bike?
And of course the clutch handle is pulled in when you go to start it, right?

Did you ever try and start it by connecting with jumper cables to a good 12 V battery, like in a NON-RUNNING car? You never answered that question or suggestion.

Do these first before you go out and buy all kinds of stuff that may not be needed. You have to start at the beginning and see if you have a good source of 12.8 V electrical power before working your way down the line and wasting your time and energy and money.
