feat: add IAgentConfigurator/IAgentHub events to eventDb

[phlgr]

Summary

• Adds 17 event signatures from IAgentConfigurator/IAgentHub to eventDb.json so that AGENT_HUB contract events are decoded in diff reports instead of showing raw topics
• Fixes undecoded events for MiscInkWhitelabel.AGENT_HUB (and any other AgentHub deployments) visible in aave-proposals-v3#996

Events added: AgentRegistered, AgentAdminSet, AgentAddressSet, AgentEnabledSet, AgentPermissionedStatusSet, AllowedMarketAdded, AllowedMarketRemoved, RestrictedMarketAdded, RestrictedMarketRemoved, PermissionedSenderAdded, PermissionedSenderRemoved, ExpirationPeriodSet, MinimumDelaySet, AgentContextSet, MarketsFromAgentEnabled, MaxBatchSizeSet, UpdateInjected

Test plan

• Re-run diff for AaveV3InkWhitelabel_ActivateRatesAndCapsAgentOnInk_20260219 and verify AGENT_HUB events are decoded

Cool that seems to work indeed.
Can you:

1. add a changeset (npx run changeset)
2. add a pr template letting ppl know to add a changeset 😅
3. make eventDb reusable for ppl relying on the package? Perhaps should be refactored from json to ts... can't recall why i made it json in first place. Probably just legacy.
