This provides a defensive upper bound to cap the effective era duration, preventing
excessively long eras from causing runaway inflation (e.g., due to bugs). If the actual
era duration exceeds this value, it will be clamped to this maximum.
Example: For an ideal era duration of 24 hours (86,400,000 ms),
this can be set to 604,800,000 ms (7 days).
Maximum allowed era duration in milliseconds.
