fix: registry list crash and logout 405

IHP NameSupport cannot parse trailing-underscore field names at runtime.
orderByAsc #label_ in all four registry list actions (and the API V2
equivalents) crashed the page with ParseErrorBundle. Changed to orderByAsc
#name which avoids the NameSupport conversion path entirely.

textField #label_ in the four registry form views has the same issue.
Replaced with a plain <input> element that reads entry.label_ directly.

Logout <a href={DeleteSessionAction}> sent GET but IHP requires DELETE.
IHP includes methodOverridePost middleware, so a POST form with
_method=DELETE handles this correctly.

Also corrected the seed admin-user migration hash from bcrypt to the
pwstore-fast format (sha256|17|...) that IHP actually uses.
