All api/*.php files include functions.php but none called session_start(),
so $_SESSION writes were lost after each request. Cart appeared to work
(API returned cart_count:1) but nothing was ever saved.

- Email::send(): add curl_error() check so transport failures (timeout,
DNS, TLS) return a diagnosable error string instead of Unknown error
- Email::send(): strip metadata key from options before array_merge so
non-API fields are never sent to CyberMail endpoint
- Email::send() + sendEmail(): include from-name in From field using
RFC 5322 "Name <email>" format so fromName DB setting takes effect
- email-log.php: replace unbounded page-link loop with a windowed
paginator (first/last 2 pages + ±2 around current) with ellipsis
gaps — prevents hundreds of anchors rendering at scale
