fix(perc-content-explorer): type relationships manager + process monitor (#2446)

[natechadwick-intsof]

Summary

Residual -Xlint batch under parent #2045 / monorepo #2200 (residual of #2384, issue #2446): type collections/iterators on PSItemRelationshipsManager and pure helpers on PSProcessMonitor.

• PSItemRelationshipsManager.loadDependencies returns Iterator<PSNode>
• Typed Iterator<PSComponentSummary> over summaries (no raw casts)
• Pure helpers: formatDependencyLabel, isAllowedRelationshipSlot, filterSummariesByContentIds
• PSProcessMonitor: isValidTotal / isValidStatus / computePercentDone pure helpers
• PSActionManager DT view: drop asNodes cast bridge at loadDependencies call site
• Tests: PSItemRelationshipsManagerTest (6), PSProcessMonitorTest (4)
• Erlang: docs/ai-generated/code-reviews/issue-2446-dce-relationships-process-monitor-erlang.md

Fixes #2446. Parent tracker: #2045.

Module remains hot (pre-existing residuals #2444, #2445, #2439 + further ActionManager/Wizard/cataloger this-escape).

Test plan

• cd modules/DesktopContentExplorer && ../../mvnw.cmd clean install — BUILD SUCCESS
• Tests run: 64, Failures: 0 (includes 10 new pure-helper tests)
• No new warnings on named files PSItemRelationshipsManager / PSProcessMonitor

Gates

• Erlang self-review: pass
• Per-module clean install: perc-content-explorer standalone
• No product behavior change intended

Operator: Grok: night-issue-prs (model grok-4.5)

Fixes #2446
