fix(bun): update Dockerfile.bun entrypoint and native bun:sqlite instantiation (#11039) (#11163)

Cherry-picked onto the current tip (authorship preserved), noise stripped. Validated on BOTH runtimes: bun test tests/unit/db-adapters/ 44/44 under the pinned Bun 1.3.14 (native bun:sqlite path), and node --test on the same suite 52 pass / 0 fail / 1 skip (Bun-only adapter skips under Node, as designed). Dockerfile.bun entrypoint now matches the standalone runner shape. Follow-up to #11039. Thank you @rqzbeh!
