Advanced Search updates

[SJuliez]

This PR

• Reworks the weapons&equipment tab so the filter summary does not vanish at the bottom of the window (not part of the scroll pane); makes the weapon and equipment tables less tall
• Adds a text filter to the weapons&equipment tab that filters the tables according to the input
• reworks all scrollpanels to be less obnoxious
• Uses FlatLaf's own tristate checkbox in the unit type tab
• On the code side, takes apart TWAdvancedSearchPanel (and removes an old copy of it that wasnt used anymore)
• moves all the search stuff into its own package

this and the later ones can be simplified with the instanceof cast from java 17

Have some ideas and suggestions.

• Some equipment with variable costs shows as -2147483648 would it be possible to just show variable. (i.e AES)

• Some weapons have negative damage (i.e. Mech Mortars) since the damage is ammo based would it be possible to show variable as well.

• One mentioned on Discord, would be it possible to add the ability to search for Movement to the Total Warfare search versus blending with Alpha Strike.

Noticed this.

Not sure if it's us not tagging the naval weapons or a filtering issue. As the NAC's seem to filter.
