fix: Move @solana/wallet-standard-features to dependencies

[s-bridges]

What kind of change does this PR introduce?

Bug fix - corrects dependency classification

What is the current behavior?

TypeScript compilation fails for users with the error:

Cannot find module '@solana/wallet-standard-features' or its corresponding type declarations

This happens because @solana/wallet-standard-features is imported in src/lib/types.ts but is incorrectly placed in devDependencies. When users install @supabase/auth-js, they don't get dev dependencies, causing the TypeScript compiler to fail when it encounters the missing module.

What is the new behavior?

TypeScript compilation works correctly. The @solana/wallet-standard-features package is now properly classified as a runtime dependency, making it available to all users who install @supabase/auth-js.

Users no longer need to manually install the missing dependency as a workaround.

Additional context

• Closes: TypeScript compilation fails: @solana/wallet-standard-features in wrong dependency section #1076
• No version changes - just moved @solana/wallet-standard-features: ^1.3.0 from devDependencies to dependencies
• This fixes the issue for all TypeScript users without affecting functionality
• The package was already being used correctly, just mis-categorized in package.json

It's probably better to inline the type and get rid of the dependency

Alternative option here #1079
