Resolve iOS pubky parity issues from #902

[ben-kaufman]

Summary

This resolves the iOS side of the pubky profile and contacts follow-up work tracked in bitkit-android#902.

What Changed

• Restored pubky session recovery from wallet backups
• Improved pubky profile and contacts flows on iOS
• Updated profile/contact edit screens and related copy
• Improved add-contact validation and pubky key handling
• Added smarter pubky clipboard and scanner routing
• Refined delete/disconnect handling for pubky profile flows

Notes

• Seed-based pubky identities reconnect from the wallet seed after restore
• External pubky sessions restore from encrypted backup metadata
• Valid pasted or scanned pubky keys now route to Profile, Contact Detail, or Add Contact before payment parsing
• Env.swift is intentionally not included in this PR

Validation

• Focused local validation was run during implementation for pubky session restore, contact/profile flows, and pubky routing

I encountered this error with pubky-ring. It seems that the problem is with the old pubkys that are in the pubky-ring. When you create/import the pubky in pubky-ring while bitkit is installed, then it works. But when you reinstall bitkit and try the same pubky - then it fails.
Scenario:

• install bitkit and create a wallet
• create pubky identity in ring
• import pubky from pubky ring -> 👍
• uninstall bitkit and install again
• create new wallet
• import pubky from pubky ring -> 👎

@piotr-iohk this looks like a Ring issue as the error is showing up there.

Did you also uninstall/ did something in Pubky Ring? Or only removed Bitkit?

Only removed Bitkit.

Just tested the exact same flow @piotr-iohk but it works well for me.
I have seen the error from the video before, but it happened to me when I tried to migrate Pubky Ring from one device to another, unrelated to Bitkit. But the flow of just deleting and reinstalling Bitkit works normally for me without error. So considering that, and that the error appears in Ring and not Bitkit, I'm quite confident it's a Ring error and not in our code.

LGTM to merge.
🙌 fot the tests.

I added a comment synonymdev/bitkit-android#902 (comment) and some subtasks - but I guess they can be addressed separately.

Actually would be good to make it consistent with Android after latest changes, since it got latest ContactsIntro with "Add Contact" button to action adding first contact (for the sake of e2e development)

Similar to the note on android: synonymdev/bitkit-android#905 (comment)

• no validation for duplicate contact addition
• the validation behavior is not consistent with the Android's when adding via scan QR (self add, invalid pubky, duplicate contact). On Android we have the "Retry" screens, no such thing on iOS.
