Resolves conflict where subscription.servers existed as both a nested
object (for server management UI keys) and a pluralization base key.
Renamed the nested object to serverManagement in all 4 locales and
updated all t() references in Subscription.tsx.
The key existed as both a string and an object in subscription
section, causing i18next to return an object instead of a string.
Removed the redundant string — serversLabel is used for plain text,
plural suffixes (_one/_few/_many/_other) handle counted usage.
