Feature request: RTTY transmit (TX) support

Title: Native RTTY TX support (keyboard-to-air)

Type: Feature request

Body:

Summary: Is there a plan to support RTTY transmit natively from within AetherSDR (keyboard-to-air, similar to the existing CW macro/keyer support), or is the intended path for RTTY TX to remain routing DAX audio out to an external program (e.g. fldigi) via a digital-mode slice?

Why it matters: CW already has a full native TX path (keyer, macros, QSK). RTTY RX is supported, but as far as I can tell there's no equivalent native TX path — just the DAX/DIGU-DIGL routing that hands audio off to a third-party application. A native RTTY TX mode (even a basic one — text entry, macros, FSK or AFSK keying) would round out the digital-mode story the way the CW suite already does for Morse.

If this is already on the roadmap, a rough sense of priority/timeline would be helpful; if not, I'd like to register interest in it as a feature request.

The issue does not name any files, tests, or entry points to investigate. Clarify the intended native RTTY TX scope and implementation path before identifying code locations and a testable definition of done.
