Add migration logic to fix corrupted relay URLs from old format

Browse Source 
When decks_cache.json was saved with the old format, relay URLs like
"wss://wot.nostr.net" were split by the ":" delimiter into separate
tokens: ["wss", "//wot.nostr.net"]. This commit adds migration logic
to detect and reconstruct these corrupted URLs during parsing.

Detection heuristic:
- If the relay_url token is just "wss" or "ws" (without "://")
- AND the next token (hashtags_str) starts with "//"
- Then reconstruct the full URL as "wss://..." or "ws://..."
- And pull the next token as the actual hashtags

This allows existing users with corrupted decks_cache.json files to
automatically have their relay URLs fixed on next app restart, without
needing to manually delete the cache file.
