Update surrealdb integration for 2.x

[alexmojaki]

Summary

• Bumps surrealdb from 1.0.8 → 2.0.0 in the lockfile.
• Updates the integration to handle PEP 604 (X | Y) unions in _is_complex_type and to derive the message template from the base SyncTemplate signature, so all subclasses share the same span template regardless of subclass-specific overrides (e.g. WebSocket connections add an optional session_id parameter in 2.x).

Why split out

This was originally part of #1898 (general dep update). It needs more scrutiny than a routine bump because the integration has to adapt to surrealdb 2.x's API surface, so it's been pinned <2 there and lives here on its own.

Test plan

• CI passes on Python 3.10–3.14
• tests/otel_integrations/test_surrealdb.py passes unchanged on both Python 3.12 and 3.14

Confidence score: 2/5

• High-confidence compatibility bug in logfire/_internal/integrations/surrealdb.py: checking types.UnionType is not Python 3.9-safe and can raise AttributeError at runtime.
• This is a concrete user-facing regression risk for Python 3.9 environments, so the merge risk is elevated despite the issue being localized to one integration file.
• Pay close attention to logfire/_internal/integrations/surrealdb.py - union-type detection needs a Python 3.9-safe approach to avoid runtime failures.
