Add PropertyLoadable/UI hierarchy bintype strings

[Crauzer]

Six hashes.bintypes.txt entries recovered while reversing the client's PropertyLoadable hierarchy.

hash	name
174c7096	UiComponent
7ec8e5ed	UiBehavior
c7a79d2b	GameScreenContainerBase
65c802be	IGameScreenNode
e75836d4	GameEntityTemplateLocatorPreview
de5dac9e	GameEntityTemplateProxyLink

FNV-1a-32 brute force, constrained by the alphabetical order of the client's static-init MetaClass_register run — registrars are emitted roughly alphabetically, so an unnamed class is bracketed by its named neighbours. All six are exact hash matches that also land in their expected registrar slot.

Supporting evidence: UiComponent's name property holds a .../Components/... WAD path whose xxHash64 equals its inherited FilepathHash; UiBehavior is the List2 element type of UiComponent's 0xa1e5aa85; GameScreenContainerBase mixes in IGameScreenNode as a secondary base at offset 32; the two GameEntityTemplate* classes register immediately after GameEntityTemplate.

Not included: 0x858de500 matches GameScreenNodeLocalizedScripts exactly but registers in the Ui* block where that name doesn't belong — treated as a coincidence until corroborated.

Sorted with LC_ALL=C per tools/hashes-prepare.

Researched and prepared with the help of an LLM; every hash was verified against shipped data.
