fix: prevent task flood caused by double OTSYS_TIME() subtraction in action delay (#3591)

Fixes a bug where `Game::playerEquipItem` incorrectly subtracted
`OTSYS_TIME()` from a delay that had already been normalized inside
`Player::getNextActionTime()`.
This caused negative or extremely large delay values (up to ~28 days),
which led to the Dispatcher scheduling massive amounts of future tasks
that would never execute.

Over time, this behavior caused exponential growth in the
`Dispatcher::scheduledTasks` queue, consuming memory and degrading
server performance.
