Is this ability a Lasting Effect (so future changes to the dial won't affect Protector's ability)?
Or is it a Delayed Effect, and the modifier is calculated during conflict resolution?

Disguised Protector is a delayed effects, and you will use the dials as they are during conflict resolution, not when the ability is triggered.

Does Disguised Protector make players add their bids to their skill totals even if there are no participating characters on their side of conflict? It does not mention a restriction like Kaito Kosori.

Disguised Protector will add both players’ bids to their skill, even if there are no characters present.

Also, does it work with Sanpuku Seidō? When at that province, characters count their glory and not their skills, but is the total still a "skill total" (to which the Disguised Protector's bonus applies), or is it now a "glory total"?

It will still apply during conflicts at Sanpuku Seidō.
