Implement ExperimentMetricsTableComponent

[zackcl]

Description:
Create a table component to display experiment metrics/queries in the experiment details page Design tab.

Requirements:

• Display metrics from experiment.queries array
• Columns:
  • Metric: Display metric key (query.metric.key)
  • Statistic: Display operation type (query.query.operationType) - may need to format/translate
  • Display Name: Display query.name
  • Actions: Edit and Delete icon buttons
• Data Source: Get metrics from experiment.queries where experiment is the selected experiment from the experiments service
• Actions:
  • Edit button: Log action for future implementation of edit metric modal
  • Delete button: Log action for future implementation of delete confirmation modal
• Empty State: Show "No metrics defined. Set up metrics to monitor for this experiment."
• Loading State: Show loading spinner when experiment data is being fetched

Questions to clarify:

• Should the Statistic column show the raw operationType value or should it be formatted/translated to be more user-friendly?
• Are there any specific formatting requirements for the metric key display?
• Should repeated measure information be displayed (query.repeatedMeasure)?

Acceptance Criteria:

• Table displays all metrics from experiment.queries
• All required columns are displayed with correct data
• Edit/Delete actions are clickable and log appropriate messages
• Empty state message is shown when no metrics exist
• Loading state is handled properly
• Component follows existing patterns and uses OnPush
