Scope requests, cache data to selected account and fetch Company info from session

[Priceless-P]

• Each request can now be pinned to a specific account instead of relying only on the current global account header.
• Cached data is now separated by account, so switching accounts cannot show data from the previous account. Account-specific cache entries are cleared on switch, while shared master account data stays available.
• The selected subaccount is saved per tab and restored after refresh. The account header is also set before the first request runs, so initial data loads for the correct account.
• Company details and KYB status now come from the session instead of placeholder values.
• Included KYB link
• User, KYB status, and Bitcoin address types match the API response directly, removing unused fallback logic. *Show user's active Bitcoin address instead of simply using the first saved address.
• Show pending KYB status in the home page. Updates proxy port to 32768 and prod url to proxy-mining.dmnd.work.
