fix #1251 - Add timers and scheduler to the DSL

[ricardozanini]

Fixes #1251

Implements spec-compliant Timeouts and Schedules, and refactors FuncDSL using a Facade pattern to delegate shared configurations to the base DSL, providing a unified developer experience.

Key Changes

• Timeouts & Schedules: Added TimeoutBuilder and ScheduleBuilder with fluent shortcuts (timeoutMinutes, every, cron, after, on). Includes strict spec validation to prevent inline/expression collisions and enforce mutually exclusive schedule triggers.

• DSL Unification: Extracted duplicated methods (Timeouts, Schedules, Auth, Event Strategies) from FuncDSL and replaced them with Facade delegates to spec.dsl.DSL. Users can now rely exclusively on import static FuncDSL.* without IDE import conflicts.

• Testing: Added DSLTimeoutTest, ScheduleBuilderTest, DSLScheduleTest, and FuncDSLScheduleTest to validate low-level builder guardrails and high-level workflow integrations.

Pull request overview

Adds spec-compliant timeout + schedule configuration to the fluent DSL (spec + experimental func), including new builders and facade methods, plus tests covering builder guardrails and workflow integration.

Changes:

• Introduces TimeoutBuilder and ScheduleBuilder and exposes fluent shortcuts via fluent.spec.dsl.DSL.
• Adds workflow/task-level .timeout(...) and workflow-level .schedule(...) support in the fluent builders.
• Adds unit/integration tests for timeouts/schedules and wires equivalent facades into FuncDSL, plus a small Maven module name tweak.
