Network proto handlers/container fixes (#6334)

Browse Source 
* Fix HP transport + some double <-> float problems

TOCLIENT_HP transport u16 hp as a u8, use u16 HP, this prevent HP over 255 to overflow across network

* Fix more double/float problem in serverpackethandler & remove implicit struct type for TileAnimationParams

* Fix connection unittests container
