Issue #3586323: Update agent edit form path in test.

Description

Fixes CI phpunit failures caused by a hardcoded agent edit form path in AiContextAgentSettingsTest::testAgentNameLinkRespectsEditAccess.

drupal/ai_agents 1.3.2 (#3586032) moved the agent admin base path from admin/config/ai/agents to admin/config/ai/tools-automation/agents. The test still asserted the old URL, so CI started failing on multiple MRs once composer resolved ai_agents 1.3.2.

Production code is already correct: AiContextAgentsForm::buildAgentNameMarkup() uses Url::fromRoute('entity.ai_agent.edit_form', ...). Only the test assertion needed updating.

Changes

• Update tests/src/Functional/AiContextAgentSettingsTest.php to derive the expected edit form path from entity.ai_agent.edit_form instead of hardcoding /admin/config/ai/agents/{id}/edit/form.

Why this is separate

This is unrelated to prefilter, scope index, or agent settings feature work. Merging it on 1.0.x lets blocked MRs rebase/cherry-pick and get green CI without mixing in unrelated changes.

Test plan

• vendor/bin/phpunit --filter testAgentNameLinkRespectsEditAccess
• vendor/bin/phpunit tests/src/Functional/AiContextAgentSettingsTest.php
• Confirm CI phpunit is green on this MR.
• Later: Merge into other open MRs and confirm CI phpunit is green (e.g. !208, !210)
