refactor: ♻️ Simplify Last look pricing checks

[timbrinded]

This pull request introduces several improvements and refactorings to the TQ Oracle codebase, focusing on price feed handling, adapter configuration, and code maintainability. The most notable changes are a major refactor of the Pyth price adapter to dynamically discover price feeds, removal of unused domain models, and updates to pipeline context and pricing logic to support configurable base assets.

Price Adapter Improvements

• The Pyth price adapter (src/tq_oracle/adapters/price_adapters/pyth.py) was refactored to dynamically discover price feed IDs from the Hermes API instead of relying on hardcoded values. This allows for more flexible asset support and reduces maintenance overhead. The adapter now uses canonicalized addresses, validates staleness and confidence intervals, and provides clearer logging for missing or stale feeds. [1] [2]
• The hardcoded PYTH_PRICE_FEED_IDS mapping in src/tq_oracle/constants.py was emptied to support dynamic discovery.

Pipeline and Context Updates

• The pipeline context (src/tq_oracle/pipeline/context.py) now supports a configurable base_asset, with a new base_asset_required property to enforce its presence. The pricing pipeline (src/tq_oracle/pipeline/pricing.py) uses this base asset instead of a hardcoded value, improving flexibility for different vaults and assets. [1] [2] [3] [4]

Codebase Maintenance

• The unused domain models (Asset, PricedAsset, TvlReport) were removed from src/tq_oracle/domain/__init__.py, simplifying the codebase.
• The Chainlink validator was removed from the price validators registry as its feeds are not exhaustive, pending future triangulation logic.

Adapter and ABI Registry Updates

• The Fee Manager ABI was added to src/tq_oracle/abi.py, with a loader function for future protocol support. [1] [2]
• The CCTPBridgeAdapter was commented out from the check adapters registry, pending Hyperliquid support.

Minor Improvements

• Logging and comments were clarified in several places, such as skipping Safe state checks if no address is configured.
• Documentation was updated to remove the stETH/ETH peg assumption warning, as the new dynamic price logic addresses this limitation.

Pull Request Overview

This PR introduces dynamic base asset discovery and Pyth price feed resolution. The oracle now discovers the base asset from the FeeManager contract instead of hardcoding ETH, and dynamically resolves Pyth price feed IDs via API instead of using static mappings.

• Adds base asset discovery via vault → FeeManager → baseAsset contract traversal
• Implements dynamic Pyth feed ID resolution using Hermes API
• Removes hardcoded Pyth price feed mappings and ETH-only assumptions
