graphql: fix parameterized account fields and block logs

[Keemosty12]

• Fix the remaining parameterized GraphQL fields that were still bound to static struct fields.
• Route Block.logs(filter), Log.account(block), Transaction.from(block), Transaction.to(block), Transaction.createdContract(block), and Block.miner(block) through resolvers so query arguments affect the returned data.
• Preserve block context while building block, transaction, and log models so nested account lookups and block-scoped log filtering resolve against the intended block.
• Add focused resolver tests for block log filtering and block-aware account resolution.

Pull request overview

This PR fixes several GraphQL fields that accept query arguments (e.g., block, filter) but were previously returning static struct data, ensuring nested account lookups and block-scoped log filtering resolve against the intended block context.

Changes:

• Forces resolvers for parameterized fields (Block.logs(filter), Log.account(block), Transaction.from/to/createdContract(block), Block.miner(block), and Block.account(address)), so arguments affect returned data.
• Preserves block/transaction context on constructed models (Transaction.Block, Log.Transaction, and Block.Logs) to support nested resolution and filtering.
• Adds unit tests covering block log filtering and block-aware account resolution.

cmd/rpcdaemon/graphql/graph/schema.graphqls	Adds @goField(forceResolver: true) on parameterized fields so gqlgen routes them through resolvers.

Thanks for the detailed review — addressed in 167c3b3228.

• Added explicit overflow guards before any uint64 -> rpc.BlockNumber conversion (blockNum > math.MaxInt64) in both account resolution and Query.Block number parsing.
• Consolidated the account-resolution helpers into resolveAccountAtBlock(...) + resolveAccountAtRequestedBlock(...) and aligned call sites.
• Fixed topic-filter semantics by removing the eager len(filter.Topics) > len(log.Topics) rejection and checking bounds only when a non-empty topic alternative is evaluated (so patterns
  like [[topic0], []] behave correctly).
• Kept the logs fallback meaningful by flattening transaction logs when obj.Logs is nil, and added tests for wildcard-topic behavior and nil-log fallback.

On the N+1 concern: agreed. I kept eager account loading in this PR to keep scope focused on correctness/behavioral fixes.
