issue 2022 slice 3e: cms.objectstore serialVersionUID after #2366 #2403

Parent / slice role

• Parent epic (perc-system javac): [8.2] Resolve javac warnings in perc-system module #2022
• Grandparent tracker: [8.2] Resolve all javadoc and javac errors and warnings #2200
• Prior slices: issue 2022 slice 3: this-escape and serial in objectstore packages #2297, issue 2022 slice 3b: residual this-escape/serial objectstore after #2297 #2313, issue 2022 slice 3c: residual this-escape/serial objectstore after #2313 #2319, issue 2022 slice 3d: residual this-escape/serial objectstore after #2319 #2366 (A–C serialVersionUID leftover — this residual)
• Slice: 3e — cms.objectstore missing serialVersionUID

Goal

Clear -Xlint:serial missing-serialVersionUID diagnostics for remaining cms.objectstore Serializable types (~40 candidates after design.objectstore UID batches completed through #2366).

Scope

• system / com.percussion.cms.objectstore (and server subpackage as needed)
• Add serialVersionUID = 1L only on types that actually implement Serializable (directly or via Serializable parent)
• Behavioral serialization unit test companion (peer: PSObjectStoreSerialVersionUidTest)
• Skip non-Serializable collection/db component subclasses without dead UIDs

Out of scope

• this-escape (separate residual)
• serial-field on large editors (separate residual)
• suppress-only without residual justification

Module

system / perc-system
