Maven hints can't be enabled again after they were disabled

[mbien]

Apache NetBeans version

Apache NetBeans 16

What happened

The org.netbeans.modules.maven.hints.pom.HintsPanelLogic and it's HintsPanel have some issues noticing when their state changes.

how it seems to work:

• the logic polls all child panels twice per second and asks if something changed
• based on that information it decides when to enable the apply button
• it also decides what to do on cancel or on ok

apply and cancel was hopefully fixed in #5009 for changes within the hint panels itself.

whats left:

• if a hint is turned off and enabled again in the same session the hint will be still off
• this can be also seen by looking at the apply button which won't switch to enabled state when the hint is checked (-> logic doesn't know that something changed)

workaround:

• restart NB
• or change something else in the options panel in addition to enabling the hint (e.g warning to error)

How to reproduce

1. open any maven hint panel
   
2. disable a hint + press ok
3. try to enable the same hint again + press ok
4. check again if it is still enabled (it isn't)

I managed to fix the rest too in the same PR. Probably no need for followups assuming everything works ok.
