Honor --no-headers for --fmt and --table output (#566)

Browse source 
`--no-headers` was only applied to `--csv`/`--tsv` output. For the tabulate
formats (`--fmt ...` and `-t`/`--table`) the flag was silently ignored, so
`sqlite-utils query db "select ..." --fmt plain --no-headers` still printed the
column-name header row.

Both `tabulate.tabulate(...)` call sites (the `query`/`memory` output and the
`rows`/`tables` output) now pass `headers=()` when `--no-headers` is set, which
suppresses the header row across every tabulate format while leaving the
default (headers shown) untouched. The CSV/TSV behaviour is unchanged.

Also clarifies the `--no-headers` help text, which previously said "Omit CSV
headers", and regenerates docs/cli-reference.rst via cog to match.

Adds test_output_table_no_headers covering --fmt simple, -t and --fmt github
for both the query and rows commands.
