feat(monitoring): added Sentry support for monitoring

[TeKrop]

Summary by Sourcery

Add optional Sentry-based monitoring and bump project version.

New Features:

• Introduce configurable Sentry DSN setting for error and performance monitoring.
• Integrate Sentry SDK with FastAPI application to capture errors, logs, traces, and profiling data when a DSN is provided.

Build:

• Add sentry-sdk with FastAPI extras as a project dependency and increment the application version.

Reviewer's Guide

Adds optional Sentry monitoring integration gated by configuration, wires it into the FastAPI app startup, introduces a Sentry DSN setting, and declares the sentry-sdk dependency, along with a minor version bump.

File-Level Changes

Change	Details	Files
Introduce optional Sentry monitoring initialization in the FastAPI app based on configuration.	Conditionally import sentry_sdk only when a Sentry DSN is configured in settings. Initialize Sentry at module import time with DSN from settings and enable default PII, log forwarding, tracing, and profiling with full sampling. Document key Sentry configuration choices via inline comments for future tuning.	app/main.py
Extend application configuration and dependencies to support Sentry.	Add a new sentry_dsn setting to the central Settings configuration with a default empty string. Declare sentry-sdk with FastAPI extras as a project dependency and bump the project minor version to reflect the new feature. Update environment/dist and lock files to align with the new configuration and dependency (if applicable).	app/config.py pyproject.toml .env.dist uv.lock

Hey - I've found 1 issue, and left some high level feedback:

• Consider making Sentry tuning parameters (PII collection, traces_sample_rate, profile_session_sample_rate, profile_lifecycle) configurable via Settings instead of hard-coding them in main.py so they can be adjusted per environment without code changes.
• Since you are depending on sentry-sdk[fastapi], you may want to explicitly use FastAPI and logging integrations (e.g., FastApiIntegration, LoggingIntegration) in sentry_sdk.init to ensure framework-specific context and logs are captured correctly.

**suggestion:** Leverage the FastAPI-specific integration from `sentry-sdk[fastapi]` to get richer context and better error reporting.

Given we already depend on the `fastapi` extra, consider initializing Sentry with the FastAPI integration (e.g. `integrations=[sentry_sdk.integrations.fastapi.FastApiIntegration()]`). This will attach richer request/response context, better transaction naming, and improved handling of background tasks compared to using the default `init` alone.

Suggested implementation:

```python
from .players import router as players
from .roles import router as roles

if settings.sentry_dsn:
    import sentry_sdk
    from sentry_sdk.integrations.fastapi import FastApiIntegration

    sentry_sdk.init(
        dsn=settings.sentry_dsn,
        integrations=[FastApiIntegration()],
        # Add data like request headers and IP for users,
        # see https://docs.sentry.io/platforms/python/data-management/data-collected/ for more info
        send_default_pii=True,
        # Enable sending logs to Sentry
        enable_logs=True,

```

If there are further keyword arguments to `sentry_sdk.init` after `enable_logs=True,` in the real file (e.g. `traces_sample_rate`, `profile_session_sample_rate`, etc.), they will remain unchanged after this edit and will continue to work as before. No additional code changes should be needed as long as `settings` is already imported and configured in this module.
