fix: use buffer-local LSP client to support monorepo workspaces

get_client() was always returning the first js_i18n client regardless of
the current buffer. In monorepo setups with per-package workspace roots,
this caused "No translation key found at cursor" errors for any package
other than the one whose client started first.

Also extract SERVER_NAME and MINIMUM_SERVER_VERSION constants into
config module for consistency.
