feat(agent-service): enable more default operator types (#4619)
### What changes were proposed in this PR?
Expand `DEFAULT_AGENT_SETTINGS.allowedOperatorTypes` in
`agent-service/src/types/agent.ts` so the agent can plan typical ETL and
visualization workflows out of the box.
- Added ETL transforms: `Filter`, `TypeCasting`, `Distinct`, `Union`,
`KeywordSearch`, `Aggregate`.
- Added visualizations: `PieChart`, `Histogram`, `Scatterplot`,
`WordCloud`.
- Removed the stale `TableLimit` entry, which does not correspond to any
`LogicalOp` subtype.
All names match the `@JsonSubTypes` discriminator names declared on
`LogicalOp` in
`common/workflow-operator/src/main/scala/org/apache/texera/amber/operator/LogicalOp.scala`.
### Any related issues, documentation, discussions?
Closes #4618.
### How was this PR tested?
Type-check only — this is a string-list config change with no behavioral
logic. Each new operator type was cross-checked against the
`@JsonSubTypes` registration in `LogicalOp.scala`.
