refactor: route ClickHouse partition SQL through the driver's dialect-aware quoting

[datlechin]

Summary

Phase 4 (R-007): ClickHousePartsView built four SQL statements with hand-rolled escaping — backtick-doubling for the table identifier and single-quote-doubling for user-supplied partition values. This routes all four through the driver's dialect-aware quoteIdentifier(_:) / escapeStringLiteral(_:) instead:

• OPTIMIZE TABLE
• ALTER TABLE ... DROP PARTITION
• ALTER TABLE ... DETACH PARTITION
• the system.parts lookup (table name used as a string literal)

Risk Addressed

• R-007: scattered, hand-rolled SQL escaping (injection surface). Partition values are user input.

Correctness

PluginDriverAdapter forwards quoteIdentifier/escapeStringLiteral to the ClickHouse plugin, which overrides quoteIdentifier to use backticks (identical to the previous output) and provides ClickHouse-specific escapeStringLiteral (more robust than the manual ''). So identifiers are behavior-preserving and the user-value escaping is strictly safer.

Verification

• xcodebuild -scheme TablePro build succeeds.
• swiftlint --strict clean.

Notes

• No test: the change delegates to the driver's quoteIdentifier/escapeStringLiteral (the tested units); the view's inline SQL lives in private SwiftUI methods.
• No CHANGELOG: output is equivalent/more-correct ClickHouse SQL, no observable user change.
• ABI bump: no. Docs: no.
