Function updateTokens

updateTokens(
    id: string,
    accessToken: string,
    refreshToken: string,
    tokenExpiry: string,
): Promise<ConnectedAccountPublic>
Refresh stored OAuth tokens for a connected account. When refreshToken is empty, the existing stored refresh token is left unchanged so a missing/empty provider value cannot wipe a still-valid grant. Returns public shape (no tokens) so callers never receive secrets.
Parameters
- id: string
  Connected account row id.
- accessToken: string
  New access token plaintext.
- refreshToken: string
  New refresh token plaintext, or empty to preserve the stored one.
- tokenExpiry: string
  ISO expiry for the new access token.
Returns Promise<ConnectedAccountPublic>
Updated public account row, or null when the row no longer exists.
