style: use indexed for over arrays/lists and [] initializers
Applies the house conventions consistently across this PR's own code rather
than leaving them half-applied: BanChannel had Register/Stop converted while
Start kept a foreach, and ConnectionFilters was foreach throughout.

Converted every foreach over an array or List, and while doing so hoisted the
_reporters/_filters static field reads into a local so the loops match the
snapshot pattern Report/Retract/ShouldDeny already use.

Left as foreach where there is no indexer: the Dictionary walks in
Firewall.ExpireEntries, PromotedGuard.Sweep and BuildAlerts, and BuildAlerts'
IEnumerable parameter.

Dictionary field initializers become [] (it compiles, same lowering). The three
remaining new List<T>(capacity) calls keep their form -- a collection
expression cannot carry the capacity hint, and all three size the list exactly.

Scoped to files this PR authored or moved; pre-existing loops in AdminGump,
Main and Utility are left alone.
