Single translation point for every error atom the sync module emits.
Call sites return plain {:error, :atom} tuples — never free-text error
strings — and the UI / API layer translates via message/1 at the
boundary. This keeps error semantics testable (you assert on the atom,
not on a string that might get reworded) and makes translations
consistent (every place that surfaces :connection_expired renders
the exact same gettext string).
Translations are in this module's own catalogue (PhoenixKitSync.Gettext,
priv/gettext). Every clause calls gettext/1 with a literal string so
mix gettext.extract sees it. Do NOT refactor this into a lookup map —
the extractor only sees literal arguments to gettext/1 at the call site.
Unknown atoms fall through to inspect/1 so the catch-all returns a
useful-if-ugly string rather than crashing.

Functions
Returns a human-readable message for an error atom, changeset, or other
value. Safe for any input — falls through to inspect/1 for unknown
terms.
The text for a transfer's stored error_message.
A reason this module classified is stored as its error atom's name and translated here, so History shows it in the reader's language; any other text (an older row, a remote site's own message) is shown as stored.
