🧹 dedust price server refactor

[zknpr]

🎯 What: Removed explicit external API call to tonapi.io for fetching the price of SCALE token against TON, replacing it with the direct inclusion of SCALE balance to the api object. Also removed the unused ADDRESSES variable import.
💡 Why: Simplifies the code, removes a fragile external API dependency in the TVL calculation, and lets the DefiLlama SDK and native price server optimally resolve token valuation.
✅ Verification: Ran node test.js projects/dedust/index.js to confirm TVL and staking values correctly printed the equivalent DUST valuation logic using the price server mapping.
✨ Result: Improved maintainability, cleaner code, and fewer external HTTP calls during adapter execution.

The adapter at projects/dedust exports TVL:

ton                       4.54 M
ton-staking               763.56 k
staking                   763.56 k

total                    4.54 M

Greptile Summary

This PR refactors the DeDust staking adapter by removing an explicit HTTP call to tonapi.io for SCALE/TON price resolution and instead passing the raw SCALE token balance directly to api.add, delegating valuation to the DefiLlama price server. It also removes the now-unused ADDRESSES import.

• The external tonapi.io API dependency (https://tonapi.io/v2/rates) is eliminated, simplifying the adapter and reducing potential failure points.
• api.add(SCALE, parseInt(get_staking_data[3])) replaces the old pattern of manually computing a TON-denominated equivalent, leaning on the price server to resolve "EQBlqsm144Dq6SjbPI4jjZvA1hqTIP3CvHovbIfW_t-SCALE".
• The return keyword was dropped from the staking function, which is fine since api.add mutates the api object in place — the caller already holds a reference to it.
• The misrepresentedTokens: true flag was already present before this PR, indicating the adapter already relied on non-standard token identifiers.
• The SCALE token constant ("EQBlqsm144Dq6SjbPI4jjZvA1hqTIP3CvHovbIfW_t-SCALE") has a synthetic -SCALE suffix rather than a real on-chain TON address. If the DefiLlama price server ever loses the mapping for this identifier, the staking TVL would silently report $0.

Confidence Score: 4/5

• This PR is safe to merge — it's a clean simplification with no new logic risks, though correctness depends entirely on an existing price server mapping.
• The change is small and well-scoped. The only implicit risk is that the SCALE token's custom synthetic identifier (-SCALE suffix) must have a valid entry in the DefiLlama price server for staking TVL to be non-zero; the author confirmed this via local testing. No new bugs are introduced.
• No files require special attention
