Adds a "Forward as attachment" action to the message overflow menu (desktop and mobile), right beside the existing "Export as .eml" action. Opens a new forward-mode compose window with the original message attached as a message/rfc822 file instead of quoted inline - useful for reporting spam/phishing to an upstream gateway that expects the raw original as an attachment (the primary motivating use case: gateways like MxGuarddog require complete original headers, including the full mail path, for scanning), or for preserving a message's exact formatting/headers when forwarding. Implementation reuses the composer's existing attachment-carry-forward mechanism (the `attachments` useState initializer in email-composer.tsx already carries a forwarded message's own attachments into the new compose via `replyTo.attachments`) - this just adds one synthetic entry representing the whole original message, referenced by its existing blobId. No re-fetch or re-upload needed, since JMAP blobs are account-scoped rather than per-email. The inline quote-header step (prepareComposerQuoteHeader) is skipped, so the body starts blank instead of quoting the original. The core "build subject + attachment entry" logic is extracted into a pure, unit-tested helper (lib/forward-as-attachment.ts) rather than left inline in the already-large page component. Adds the forward_as_attachment locale key to all 24 locales (English text as a placeholder pending translation, following the existing add-a-key convention) to satisfy the translations completeness test.
