* fix(control-ui): stop config form save from corrupting 64-bit id strings

Saving the schema-driven config form coerced every numeric-looking string
to a JS number before submission. For union-typed fields such as
tools.elevated.allowFrom.* (anyOf: string | number), string entries
holding 64-bit ids (Discord/Telegram snowflakes) were rewritten through
Number(), which rounds past 2^53:
"1048113311314608148" -> 1048113311314608100. The corruption also hit
untouched fields, because serialization coerces the whole form, so merely
saving an unrelated setting silently broke elevated-approval allowlists
(fail-closed: the real user id no longer matched).

Two guards fix this:
- coerceFormValues keeps a string that already satisfies a string variant
  of an anyOf/oneOf union instead of parsing it into another variant's
  number.
- coerceConfigFormNumberString refuses lossy integer parses: plain
  integer text beyond Number.MAX_SAFE_INTEGER that does not round-trip
  through BigInt stays a string, so pure number/integer fields fail
  validation loudly instead of storing a corrupted id.
