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.

 ## Database Connection Check
 
+The IHP Nix image has no `/bin/sh`. Connect via the CNPG pod instead:
 ```bash
-kubectl exec -n inter-hub deploy/inter-hub -- \
-  /bin/sh -c 'psql $DATABASE_URL -c "SELECT version();"'
+kubectl exec -n databases net-kingdom-pg-1 -- psql -U postgres -d interhub -c "SELECT version();"
+```
+
+## Password Hashing
+
+IHP uses `pwstore-fast` (`Crypto.PasswordStore`) — **not bcrypt**. Hash format:
+```
+sha256|17|<base64-salt>|<base64-hash>
+```
+
+To generate a correct hash (requires GHC with pwstore-fast available on haskelseed):
+```bash
+ssh root@192.168.178.135
+cat > /tmp/genhash.hs << 'EOF'
+import qualified Crypto.PasswordStore as PS
+import qualified Data.ByteString.Char8 as B8
+main :: IO ()
+main = do
+    h <- PS.makePassword (B8.pack "yourpassword") 17
+    B8.putStrLn h
+EOF
