fix(analytics): Harden analytics setup

[charlesvien]

Changes

1. Pass main-minted session id via additionalArguments and init PostHog synchronously
2. Bind AnalyticsBootContribution first so init runs before render and all effects
3. Gate boot-time analytics reset on bootstrapComplete to stop wiping the persisted distinct_id
4. Fire buffered flag listeners at init so cached flag values apply without waiting for /flags
5. Remove now-unused getSessionId tRPC procedure
6. Add tests for the reset gate and listener buffering

T-Rex Logs

What T-Rex did

• Traced the session-id flow from the Electron main process through preload exposure to renderer initialization to confirm correct argument handling.
• Verified the analytics boot contribution is bound first and that contributions are executed in sequence so PostHog initializes before other renderer contributions.
• Examined feature-flag listener buffering, including pre-init subscribe, unsubscribe before and after init, and delivery of cached flags.
• Validated the useAuthIdentitySync gate ensuring analytics reset is skipped while the auth bootstrap is incomplete.
• Attempted to run existing tests with vitest but the run was blocked by Node version incompatibility with the repository toolchain.
• Created a targeted analytics boot and feature flag validation notes artifact to document the checks.
