New [Parkour] Make round timers consistently 30 minutes across maps

[james bond]

This refers to a previous issue I've noticed where the maps on the parkour server have inconsistent round timers. For example:
par_raiders and par_hell_lands have 10 minute timers
par_nyanko has a 15 minute timer
par_parkour_paradise has a 30 minute timer
The shorter timers can cause a good run on the map to end prematurely if it's simply started too late into the map's runtime. To help with this, making the rounds on each map have a 30 minute timer (the same as the server's map timer) would give more time for the players to try beating the map.

Sometimes these timers are deliberate. Par_world has a deliberate timer set to 10 minutes. You have 10 minutes to beat the map, or you all lose.

par_raiders has a 10 minute timer because func_rotating will stop rotating after so long so it forces the map to reset before that happens.
