Does Dahan on their Guard *(In each land, 1 Defense per Dahan)* provide Defense based on the number of Dahan at the time the Fear card was revealed or when the Ravage happens?
For island-wide effects like Dahan on their Guard, you check the number of Dahan there when the Invaders do damage (usually in the Ravage).
This applies to all Event / Fear cards that affect all lands with (some contents) - you treat it as a game-wide rule for the turn, so you don't have to keep track of where pieces used to be across the entire board. Powers which affect all lands of a particular type work the same way, for the same reason.
Powers which affect only one land check land contents at the moment of use, again to minimize required memory: it's easier to remember "this specific land has Defend 3" than "this land has Defend equal to the number of Dahan in it at the time".
Unusual cases:
- The Coordinated Strikes Event checks "are there 3 or more Dahan?" immediately to see where Damage happens, then again later on (when it's relevant) for the Defend.
- The Trees and Stones Speak of War Major Power provides per-Dahan Defense that moves with the Dahan if you hit the threshold (because the threshold explicitly says so).

Are the extra Builds from Bureaucrats Adjust Funding part of the normal Build for the purposes of Panicked by Wild Beasts?
Yes, if it's the first Build Card that turn, Panicked by Wild Beasts level 2 or 3 skips any additional Builds caused by Bureaucrats Adjust Funding.
Bureaucrats Adjust Funding modifies how the Build Card works, and thus any additional Build Actions it causes are considered part of the normal Build Card.
