feat(source/databaseinsights): add databaseinsights source - #3461

…3461)

## Description

Adds the new `databaseinsights` source to configure an authenticated
HTTP client to connect to `databaseinsights.googleapis.com` using
Application Default Credentials (ADC).
This source provides the connectivity layer to fetch advanced query
insights for AlloyDB, which is supported by the remote [AlloyDB Database
Insights MCP
server](https://docs.cloud.google.com/alloydb/docs/reference/mcp/databaseinsights/mcp).

This PR introduces only the core connectivity and authentication layer.
The 5 specific database insights tools will be added in subsequent PRs.

…lloyDB (#3722)

## Description
    
Adds MCP tools for Advanced Query Insights in AlloyDB allowing users to
analyze database query performance, wait event bottlenecks, time series
metrics, and fetch index recommendations.
  
> **Note**: This PR is stacked on top of PR
[#3461](#3461)
(`feat/add-databaseinsights-source`). Which adds the database insights
API source.
    
### Summary of Tools Added:
• get_advanced_aggregated_query_stats: Fetches aggregated query
execution statistics.
• get_advanced_aggregated_wait_event_stats: Fetches aggregated wait
event bottleneck metrics.
• get_advanced_time_series_query_stats: Fetches time series performance
metrics for queries over time.
• get_advanced_time_series_wait_event_stats: Fetches time series metrics
for wait events over time.
• get_index_recommendations: Fetches index recommendations to optimize
query performance.
  
These tools are already available via the Google-hosted remote OneMCP
server
https://docs.cloud.google.com/alloydb/docs/reference/mcp/databaseinsights/mcp

### Key Changes:
- **Tool Implementation**: Implements the Advanced Query Insights Tools
using databaseinsighst source. These are already available via the
OneMCP server
https://docs.cloud.google.com/alloydb/docs/reference/mcp/databaseinsights/mcp
- **Prebuilt Config**: Added tools to
`internal/prebuiltconfigs/tools/alloydb-postgres-observability.yaml`.
- **Documentation**: Added tool guides and structural index file under
`docs/en/integrations/databaseinsights/tools/`.
- **Unit & Integration Tests**: Added unit tests with mock sources and
an integration test suite (`tests/databaseinsights/`). The test uses
`DATABASE_INSIGHTS_*` environment variables (or falls back to
`_ALLOYDB_POSTGRES_*` cluster and instance variables in Cloud Build)
where the test instance **should have Advanced Query Insights enabled**,
and gracefully skips locally if environment variables are omitted.
