The recording e-mail's subject and body round-tripped through EmailSettings and
the backend (keyEmailSubject/keyEmailBody) but had no UI editor — only the QSL
card e-mail did, so the recording mail was stuck on the default text. Add the
same subject/body editor to the E-mail panel, above the QSL block, sharing the
{CALL}/{DATE}/{BAND}/{MODE}/{MYCALL} template variables.
