fix(actions): generate unique tags for each action instance (#59)

[MohamedRady-99]

Notes for Reviewer

This PR resolves the issue where all actions of the same type (e.g., Sequence, Concurrency, Graph) share the same Tag ID when printing the program
representation #59.

Since every instance of a given action type initialized its ActionBaseMeta using a hardcoded static string (such as "orch::internal::sequence"), they
all computed the exact same Tag ID (via djb2 hash). This made different instances of the same action type indistinguishable in printed representations
and debugging logs.

Proposal:

Currently, actions share identical static tags. This PR updates the tag initialization logic as follows:

• Centralized Unique Tag Generator: Added next_unique_action_tag(prefix: &str) in src/orchestration/src/actions/action.rs using a thread-safe
  AtomicUsize counter to append a unique incrementing suffix to each action instance's tag.
• Update Core Actions: Updated builders and constructors across all core action types (Sequence, Concurrency, LocalGraphAction, Select, IfElseArc,
  IfElseArcMutex, Catch, Sync, Trigger) to use next_unique_action_tag.
• Clean up Warnings: Removed now-unused Tag imports in sync.rs and trigger.rs to ensure a clean, warning-free build.
• Add Unit Test: Added test_unique_tags_for_actions inside sequence.rs to assert that separate built actions have distinct, non-overlapping Tags.
