Release v2.6.2 for KSP 1.12.x · KSP-RO/RP-1

What's Changed

Switch to a general integration cost for hazardous resources rather than the old per-part system. This should reduce spiky values for service modules and the like. This should result in similar integration times to before the changes to resource multipliers, except for a decrease in integration time for crewed vessels with fuel cells and hypergolics by @NathanKell
Fix an issue where a previous fix to subsidy calculations was only cosmetic, leading to lower than designed subsidy
Fix the Reputation tooltip overestimating reputation decay
Fix predicted subsidy in the Budget screen not taking leaders into account when predicting reputation decay
Fix Comm Test and Early Comm Satellite contracts not counting as optional for the Comm Network program
Refresh the Integration Info window when unlocking a part or upgrade
Fix the Fund Target in the Combined tab of Space Center Management not clearing correctly
Speed up rendering of the Combined tab
Mention the use of Shift (x10), Ctrl (x100), and Alt (Max Possible) for staff changes in the Staff window

Unstick HasCrewCapacity in contracts by @Teykn in #2113
