Harmonized table output across commands using tabled

[evoggy]

Every command that printed a table rolled its own, with hardcoded column
widths: param list padded names to 30 characters, log list to 30, lps
used a different two-space style, mem list wasn't columnar at all, and
deck list had a third variant. A value longer than its hardcoded width
pushed the row out of alignment.

This switches them all to tabled behind
two helpers in utils::display:

pub fn table<I>(rows: I) -> Table where I: IntoIterator, I::Item: Tabled
pub fn print_table(table: &Table)

table() applies the house style in one place — | separators, a dashed rule
under the header with + junctions, columns sized to their content. print_table() prints it
without trailing whitespace. Rows are described with #[derive(Tabled)]
structs, so the column headers live next to the data instead of in a format
string.

Converted: param list, param get, log list, mem list, loco display,
the anchor-positions file listing, and deck list (which drops the hand-rolled
helper added in #18).

Deliberately left alone: test.rs, scan, lighthouse and bootloader info
print label/value blocks and single-column lists, not tables — forcing those
into a grid would read worse.

The style is unchanged in spirit but columns now fit their content:

$ cfcli mem list
ID | Type         | Size                    | Serial
---+--------------+-------------------------+------------------
 0 | EEPROMConfig | 8191 (0x1fff)           |
 3 | OneWire      | 112 (0x70)              | 0D0AB362010000CA
 4 | DeckMemory   | 1342177280 (0x50000000) |

mem list is the one visible format change — it used to print
[0] EEPROMConfig size=7k (0x1fff/8191) per line.

Numeric columns (mem list ID, anchor IDs) are right-aligned and param's
Access column stays centred, as before.

All --csv output paths are untouched.

Dependency

tabled adds 6 crates to a 440-crate tree (tabled, tabled_derive,
papergrid, bytecount, fnv, testing_table). unicode-width, syn,
quote and heck were already present via indicatif/inquire. It also fixes
display width for wide characters, which the hand-rolled version got wrong.

Testing

param list, param get, log list, mem list and deck list verified
against a Crazyflie with a Lighthouse deck attached; the anchor-positions
listing against a file. Empty result sets render as header + rule, as before.

The doc examples in docs/memory.md, docs/logging.md, docs/parameters.md
and docs/deck.md are updated to match the new output.
