feat(fault_pack): promote aborted action goals to faults

[mfaferek93]

For the core stacks (Nav2, MoveIt 2, ros2_control), the authoritative failure is the action result, not /rosout or /diagnostics. A MoveGroup / NavigateToPose abort emits no /rosout ERROR and there is no /diagnostics, so log- and diagnostic-based rules miss it entirely. Catch it generically via the goal-status channel.

Scope

• Discover every action via its */_action/status topic (action_msgs/msg/GoalStatusArray); rescan the graph for actions that appear later.
• ABORTED (6) -> fault (default SEVERITY_ERROR); CANCELED (5) -> fault only if canceled_is_fault; SUCCEEDED (4) -> PASSED to heal the action's ABORTED code.
• fault_code = <PREFIX>_<ACTION>_ABORTED; source_id = action name.
• Per-goal dedup keyed on goal_id so a latched terminal status reports once.
• Reporter local filtering disabled for these terminal events (an abort is discrete, not flapping) so a single recovery heals reliably.

Acceptance

• An unreachable MoveGroup / NavigateToPose goal produces ACTION_<name>_ABORTED CONFIRMED in list_faults, source = action name.
• A subsequent successful goal heals it to HEALED (FaultManager healing_enabled).
• A MoveIt abort produces the action fault with zero LOG_* faults present (the action channel is the only signal).
• Unit tests: action-name extraction from the status topic, fault_code, uuid/dedup.
