fix(perc-system): type server.cache raw collections (#2877)

[natechadwick-intsof]

Summary

Partial fix for #2877 (parent epic #2022, grandparent #2200, residual of #2299).

PR-sized com.percussion.server.cache -Xlint rawtypes/unchecked batch with real generics.

Changed

• PSContentItemDependencyTree — Map<Integer,List<PSItemDependency>>, typed List<String[]> dependency results, Map<Integer,Integer> done maps, ItemSet extends HashSet<Item>
• PSMultiLevelCache — nested Map<Object,Object> cache tree, typed listener lists
• PSAssemblerCacheHandler / PSResourceCacheHandler — Map<String,?> flush/validateKeys; typed dependency flush lists; resource dep tree maps
• IPSCacheHandler / PSCacheHandler / PSCacheManager — flush/validateKeys Map<String,?>
• PSKeyRules, aging/memory managers, proxies/exits, PSItemSummaryCache folder-id lists
• Test: PSServerCachePackageTypedTest

Out of scope (residual)

• issue 2022 slice 5i: residual perc-system Xlint after server.cache (#2877) #3160 — remaining server (non-cache) / services / security / xml-extension residual under [8.2] Resolve javac warnings in perc-system module #2022

Test plan

• cd system && ../mvnw.cmd test -Dtest=PSServerCachePackageTypedTest,PSMultiLevelCacheTest → Tests run: 7, Failures: 0
• cd system && ../mvnw.cmd clean install → BUILD SUCCESS, Tests run: 1955, Failures: 0, Errors: 0, Skipped: 241
• No new product-facing behavior; typing only

Gates evidence

• modules_built: system
• build_evidence: cd system; ../mvnw.cmd clean install → BUILD SUCCESS; Tests run: 1955, Failures: 0, Errors: 0, Skipped: 241
• downstream_checked: grepped monorepo for PSCacheManager.flush / validateKeys / PSCacheProxy.flush*; in-module callers already use Map<String,String> or no-arg flush; generics erasure preserves binary callers (CacheProxy static helpers)

Product documentation

• N/A — pure tech-debt generics/-Xlint cleanup; no operator/user/API behavior change

Partial for #2877 — residual #3160 filed for remaining perc-system packages.

system/src/main/java/com/percussion/server/cache/PSItemSummaryCache.java	940	Comment references ids[i++] but the removed code used ids[i] = idList.get(i) with no double-increment. The comment describes a bug from an earlier version, not the code just removed.

WARNING

File	Line	Issue
system/src/main/java/com/percussion/server/cache/PSItemSummaryCache.java	940	loadFolderAcls contains an unintended behavior change — the old ids[i++] = id; was a latent bug that skipped every other folder ID, and the new ids[i] = idList.get(i); fixes it. This is an unannounced behavioral change in a PR described as having "no operator/user/API behavior change".
system/src/test/java/com/percussion/server/cache/PSServerCachePackageTypedTest.java	111	`assertTrue(!owners.hasNext()

SUGGESTION

File	Line	Issue
system/src/main/java/com/percussion/server/cache/PSContentItemDependencyTree.java	528	getOwners return type changed from raw Iterator to Iterator<Integer>. While bytecode-compatible via erasure, this is a source-level public API change. Since the method is only used within the package (from the new test), practical risk is low, but it deviates from the PR's stated "no API behavior change" goal.
