perf(core): optimize unstranslated strings representation

`TranslationStringsChunk` is used for storing English strings more efficiently.

Otherwise, every &str[^1] takes 32-bit pointer & 32-bit length, resulting in ~8kB = (8 bytes x ~1k strings).

The short version

What changed, and why it matters

This commit is a straightforward memory-optimization refactor. It replaces a large lookup table of individual English strings with a more compact packed representation, reducing firmware size by about 8 kB. There is no user-facing behavior change and no security fix or vulnerability introduced.

Recommended action

No security action needed; treat as normal code-review/QA for correctness of generated offsets and ASCII packing.

Security signals we found

No strong security signals were identified.
