Review creation and logging of SuperToken list

[d10r]

On startup, the sentinel logs a list of SuperTokens.
First, there's an info log of all SuperTokens it's aware of (?), followed by a debug log of the same with 3Ps info attached.

This list seems to not be in sync with the list of tokens configured for the sentinel.
There's currently 3 ways to affect the list of tokens taken into consideration (lets call it "watched SuperTokens") by a sentinel instance:

• config item ONLY_LISTED_TOKENS (deprecated via Remove filter for listed SuperTokens #201)
• config item TOKENS (positive filter)
• config item EXCLUDED_TOKENS (negative filter)

If none of those are set - which is the default - all SuperToken are in the set of watched SuperTokens.

2 issues to be investigated:

• Currently, the report outputs a set of SuperTokens which doesn't reflect the set of watched SuperTokens.
• It doesn't reflect the set of all SuperTokens either. E.g. on some instances running for Polygon I see the SuperToken EURSx (0x02ef6868d69707b6093a2962bb5fe5661fcc0deb) missing, despite it not being included, despite it being a listed token. (may be related to the handling of the listed flag in previous sentinel versions) (this is likely a snapshot creation issue, to be dealt with separately) it's because no CFA event happened yet, keeping the token invisible for the sentinel

Goal:
going forward, the report item protocol.supertokens should reflect the current list of watched SuperTokens, such that sentinel operators can easily verify it's reflecting the intended configuration.
