fix(spells): correct the fear condition

PF1e (SRD spells/fear.md): creatures become panicked unless they succeed on a Will save - the JSON applied frightened instead. Condition fixed to panicked. The shaken-for-1-round on a successful save needs partial-save support for conditions and the 30-ft cone needs a cone template, neither of which the engine has; both documented in README as out of scope rather than built.
