[loadgen] Allow bare number as const distribution shorthand

- New feature

Add a mapstructure decode hook so a bare number is accepted as a
shorthand for a const distribution. For example:

    read-write-count: 2

is now equivalent to:

    read-write-count:
      const: 2

The hook targets the workload.Distribution type, so the shorthand
applies uniformly to every distribution config field (read/write
counts, query-size, min-invalid-keys-portion, dependency gap).
Non-numeric values (maps, strings, booleans) are left untouched, so
the full distribution forms (const, uniform, normal, discrete,
bernoulli) keep working.

- Documented the shorthand in the loadgen sample config and switched
  the read-write-count example to it, which makes the existing
  sample-loading test cover the shorthand end-to-end through the real
  config loader.
- Added decoder unit tests for the shorthand (int/float/negative/zero),
  regression tests for the explicit forms, and a guard test ensuring a
  non-numeric scalar surfaces a decode error rather than being coerced.

 - resolves #673
