Readonly access to trader positions based on URL

[vvp]

I noticed some other apps are using the URL fragments to read the address/identifier to display information about the contract status (instead of using only address from the connected wallet). For example:

• https://app.uniswap.org/#/pool/12345 lets you inspect the trading status for NFT id 12345
• https://rinkeby.gnosis-safe.io/app/#/safes/0xEA7E95b1A49Fbb472Ad2c0a3000DFF9e40Ec5184/ shows the status for the safe in address 0xEA7E95b1A49Fbb472Ad2c0a3000DFF9e40Ec5184 etc

The biggest benefit is that as a trader, I don't need to connect my wallet to inspect my positions, which is both

• convenient as I can check how my positions are doing just by refreshing the page (safe to assume inspecting the portfolio happens far more often than executing any trades) - especially nice with wallets that work better on desktop, so you can trade on desktop and check your portfolio on mobile
• safer as I need to keep the wallet connected far less often which reduces the attack surface considerably

So, let's support this in Vanilla too! 🙂 I propose URLs like https://vanilladefi.com/#/portfolio/<traderaddress>.

This should not be violating any confidentiality or anonymity either, as we're still operating only public Vanilla contract data and URL fragments (basically everything after #) are processed local-only and not sent to the server. We do need to add some history management into app, which will add some complexity.
