2-57-3 states that a player who violates the CR rule is an illegal substitute. Rule 3-4 will be your guide for determining what penalties should apply.

Of course preventive umpiring would (should) have caught this, but what if any recourse or penalty could be applied when the home questioned this?

While it's a little unclear in your OP, it appears the VC put her at 1B as a CR. Your right in saying the home team was too late in bringing this to your attention. Had they said something while the runner was on base, the CR is an illegal sub and is restricted for the remainder of the game. (3-4-1c)

Would there be an un-reported sub somewhere?

No. The VC put her out there as the CR. Of course preventative umpiring dictates if we as umpires know a player can't CR for the "new" catcher, we prevent it. But you can't "retroactively" determine she was actually a sub.

Did the (improper) CR become a sub once she took first base? If the new catcher comes in on defense is she now an unreported sub? (if CR becomes sub).

No. See above.

Do you just tell the home coach it is to late to fix, you should have told me sooner?

Yep.
