In `@proxy/config/config.go`:
- Around line 27-29: IsRHEMEnabled is an exported function lacking a godoc
comment; add a concise godoc comment immediately above the IsRHEMEnabled
function explaining what it checks (reads the IS_RHEM env var) and what the
boolean return value represents (true when IS_RHEM == "true", false otherwise),
so the exported API is properly documented for users and tools.

In `@proxy/server/settings.go`:
- Line 19: The call to json.NewEncoder(w).Encode(settings) currently ignores its
error; modify the handler that writes settings (the code using
json.NewEncoder(w).Encode(settings), referencing variables w and settings) to
check the returned error, log or record it, and return an appropriate HTTP error
status instead of silently continuing: if Encode fails, write a 500 response
(e.g., http.Error or w.WriteHeader(500) + an error body) and ensure no 200
response is sent; otherwise continue to write the successful JSON as before.
- Around line 14-20: The UISettingsHandler currently serves a top-level public
endpoint and swallows the JSON encode error; add an explicit comment above
UISettingsHandler documenting that this endpoint is intentionally public
(registered on router, not apiRouter), that it only exposes the deployment-wide
flag returned by config.IsRHEMEnabled() and must never include org/user-specific
data, or alternatively move its registration to apiRouter if it should require
middleware.AuthMiddleware/middleware.OrganizationMiddleware; then fix the
ignored encoder error by capturing the return value from
json.NewEncoder(w).Encode(settings) and handling it (log via your existing
logger and respond with an appropriate http error/status if encoding fails).

In `@proxy/server/settings.go`:
- Around line 17-23: The handler currently streams JSON directly with
json.NewEncoder(w).Encode(settings), which can commit a 200 before Encode fails;
instead marshal the payload first (e.g., json.Marshal or json.MarshalIndent)
into a byte slice, check the error, and only after successful marshal set the
Content-Type header and write the bytes to w (optionally set Content-Length).
Update the uiSettings write path to replace json.NewEncoder(w).Encode(settings)
with pre-marshalling and return http.Error(..., http.StatusInternalServerError)
only if marshal fails.

In `@proxy/server/settings.go`:
- Around line 26-27: The write error from w.Write(payload) is being ignored;
update the handler containing the w.Write call to log the error before returning
— e.g., capture err from w.Write(payload), call the existing logger (or the
standard log package) like logger.Errorf("write response failed: %v", err) or
log.Printf(...) and then return; reference the w.Write(payload) expression and
its enclosing function to locate where to add the logging.

Inline comments:
In `@proxy/app.go`:
- Around line 75-77: The /ui-settings route gating in app.go is using a raw
string comparison on config.OcpPlugin, so normalize IS_OCP_PLUGIN before this
branch instead of checking only for "true". Update the config handling in
proxy/config/config.go or the route registration logic in app.go so values like
TRUE, 1, or yes are treated as enabled, and keep the change anchored around the
existing OcpPlugin and UISettingsHandler path registration.
