feat: make lp opportunities great

[gomesalexandre]

Description

Many birds, one stone:

• Fixes Portals parsing so that LP read-only opportunities have their LP meta actually upserted in opportunities.lp.byId (they weren't before, and all were upserted as staking)
• Fixes LP opportunities selectors so that the correct ID is used for introspection, i.e underlyingAssetId (the top-level asset, basically an LP token) vs. the opportunityId (a composite AssetId of sorts).
  Using said composite ID means we were trying to introspect assets[compositeId], failing, early returning, and effectively not having the opportunity as part of LP ones. The reason it "worked" previously was accidental, as a direct consequence of the above.
  First of all, it did not work before. It only worked in "By Provider", not in "By Asset" but we'd never noticed. The reason it worked there is because "By Provider" is more dumb and doesn't use staking/id indexes for rendering but simply rendered all opportunitie indexed by provider, with no regard for their DefiType.
  In comparison, the 'By Asset' view has two "Staking" and "LP" tables, which uses each index and then introspects things, which is where this fix comes in
• Adds the same "View"/"Manage" logic as below in feat: savers read-only opportunities #8878, this time for LP, not staking
• Ensures that both LP and staking tables do not render any button (View/Manage) if there's no link, which read-only opportunies do not have following the switch to Portals

Issue (if applicable)

• relates to Clean up earn page #8866
• closes Read-only show up as empty in earn 'By Asset' when expanded #8875
• closes The 'manage' button for Read Only positions in the Earn page is a dead click #8883
• closes "Start Earning" does nothing #8884

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

Testing

• Test with a wallet that has read-only opportunities (any degen wallet will work) or your own if you have LP tokens (can swap to some using TraderJoe if you don't)
• Ensure that you can see your LP read-only opportunities in the DeFi section, vs. empty when expanding previously
• No LP opportunities are displayed as Eligible in the dashboard
• There is no dead link button in opportunities (View/Manage)

✅ No LP opportunities are displayed as Eligible in the dashboard
✅ There is no dead link button in opportunities (View/Manage)

Noting that we still have the wagmi issue (I think due to missing assetReference for some assets), but that is not a regression in this PR.

Also 2 nitpicks I'd prefer to see fixed.
