fix(cli): render spec-required panels in agents plan apply rich output

Implemented a dedicated rendering path for the apply command to display all spec-required Rich panels in a cohesive, rich output experience.

What was implemented
- Added _print_apply_rich_output() in src/cleveragents/cli/commands/plan.py to render all five spec-required Rich panels (project_links, validation_summary, sandbox_refs, timestamps, error_details) using data from the Plan model.
- Updated lifecycle_apply_plan() (the @app.command("apply")) to invoke _print_apply_rich_output() instead of the generic _print_lifecycle_plan(), aligning the apply flow with the enriched plan output.
- Updated _lifecycle_apply_with_id() helper for consistency with the new rendering path.
- Added feature test features/plan_apply_rich_output_panels.feature with eight scenarios covering all panels and a robust step definitions file at features/steps/plan_apply_rich_output_panels_steps.py.

Key design decisions
- Created a dedicated _print_apply_rich_output() rather than modifying _print_lifecycle_plan() to keep concerns separated and minimize impact on existing lifecycle output paths.
- Panels draw from Plan model data: project_links, validation_summary, sandbox_refs, timestamps, and error_details, ensuring the rich output reflects the actual plan state.
- Duration formatting uses HH:MM:SS to match the specification.
- Implemented graceful fallbacks for missing data by displaying a dash-like placeholder for unavailable timestamps and other absent fields, ensuring stable, readable output.

+Feature: Issue #2618 — agents plan apply rich output spec-required panels
+  As a developer using the CleverAgents CLI
+  I want ``agents plan apply`` to render the five spec-required Rich panels
+  So that I can see Apply Summary, Validation, Sandbox Cleanup, Plan Lifecycle,
+  and Next Steps after applying a plan
+
+  These scenarios verify that the rich (default) output format for
+  ``agents plan apply`` renders all five panels required by the specification,
+  replacing the previous generic ``_print_lifecycle_plan`` fallback.
+
+  Background:
+    Given a plan apply rich output CLI runner
+    And a plan apply rich output mocked lifecycle service
+
+  Scenario: Apply Summary panel is rendered in rich output
+    Given a plan ready for apply with project "local/api-service"
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Apply Summary"
+    And the apply rich output should contain "local/api-service"
+    And the apply rich output exit code should be 0
+
+  Scenario: Validation panel is rendered in rich output
+    Given a plan ready for apply with validation summary
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Validation (from Execute)"
+    And the apply rich output exit code should be 0
+
+  Scenario: Sandbox Cleanup panel is rendered in rich output
+    Given a plan ready for apply with sandbox refs
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Sandbox Cleanup"
+    And the apply rich output should contain "removed"
+    And the apply rich output exit code should be 0
+
+  Scenario: Plan Lifecycle panel is rendered in rich output
+    Given a plan ready for apply with lifecycle timestamps
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Plan Lifecycle"
+    And the apply rich output should contain "Total Duration"
+    And the apply rich output exit code should be 0
+
+  Scenario: Next Steps panel is rendered in rich output
+    Given a plan ready for apply with project "local/api-service"
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Next Steps"
+    And the apply rich output should contain "Review git diff"
+    And the apply rich output exit code should be 0
+
+  Scenario: Confirmation line is rendered in rich output
+    Given a plan ready for apply with project "local/api-service"
+    When I run plan apply with rich output
+    Then the apply rich output should contain "OK"
+    And the apply rich output should contain "Changes applied"
+    And the apply rich output exit code should be 0
+
+  Scenario: All five panels are rendered together in rich output
+    Given a plan ready for apply with all rich output data
+    When I run plan apply with rich output
+    Then the apply rich output should contain "Apply Summary"
+    And the apply rich output should contain "Validation (from Execute)"
+    And the apply rich output should contain "Sandbox Cleanup"
+    And the apply rich output should contain "Plan Lifecycle"
+    And the apply rich output should contain "Next Steps"
+    And the apply rich output exit code should be 0
+
+  Scenario: JSON format still works and does not render panels
+    Given a plan ready for apply with project "local/api-service"
+    When I run plan apply with json format
+    Then the apply rich output should not contain "Apply Summary"
+    And the apply rich output should not contain "Sandbox Cleanup"
+    And the apply rich output exit code should be 0
