This change skips update intervals when the GUI cannot obtain a lock for "cs_main". It avoids stalling the GUI thread when a long-running operation holds the mutex for: - The overview page refresh - The researcher context refresh
This optimizes how the GUI determines the "mined" type of a coinstake transaction. It reorganizes the lookups to avoid the cs_main locks if the node is busy with another operation. This prevents GUI stalls for routine updates of the overview and history pages from core state. It prevents the long-running polls load on the voting page from bricking the GUI thread.

These changes skip periodic update intervals with conditional locking and optimize how the GUI determines the "mined" type of a coinstake transaction (#1390). The
GetGeneratedType()function was called from presentation routines on the Qt side that did not expect synchronization with the core wallet state. The PR reorganizes the look-ups to avoid thecs_mainlocks if a node is busy with another operation. This avoids GUI sluggishness for recurring updates of the overview and transaction history pages from core state and prevents the long-running polls reload on the voting page from bricking the GUI thread. More optimizations for poll performance will come with caching in a later PR.
