fix(login): Resolve dashboard connection delay with robust loading state

[ChitkulLakshya]

Root Cause Analysis

Users have frequently experienced a 1 to 2 minute UI 'freeze' when clicking the Continue to Dashboard button on the Login page if an active session is detected. This happens because the backend API (/api/users/me) can experience Serverless cold starts or network latency, taking up to 2 minutes to respond on free tiers. The frontend \handleContinue\ function lacked any visual feedback during this asynchronous wait, leading to a degraded UX where the app appeared unresponsive.

Proposed Changes

This PR systematically addresses the lack of UI feedback by breaking down the solution into three distinct commits:

1. Refactored \handleContinue: Wrapped the asynchronous \postLoginRedirect\ call in a \ ry-finally\ block, injecting a \loading\ state boolean that toggles seamlessly during the network request.
2. Disabled Button State: Bound the \loading\ state directly to the Continue to Dashboard and Switch Account buttons. This crucially prevents duplicate submissions and prevents the user from clicking away while the backend spins up.
3. Visual Spinner Implementation: Substituted the static \ArrowRight\ icon with an animated \RefreshCw\ spinner when the loading state is true, simultaneously updating the button text to 'Connecting...' to provide immediate, actionable feedback to the user.

Verification

• Clicked 'Continue to Dashboard'.
• Button immediately disabled.
• Spinner activated with 'Connecting...'.
• UI remained in loading state until the backend returned the payload, then properly routed to /dashboard.

Note: The underlying cold-start issue itself is being mitigated at the infrastructure level via UptimeRobot pings to the backend API base URL.
