UX-02: the panel was weaker than the startup gate for one field
Applying review finding N1, which was non-blocking because it fails closed, and
N2, which is a fabricated number.

N1. Clearing the `max_w` box answered HTTP 500 on a non-JSON body, which the
page rendered as "cannot reach the add-on" - untrue, and for the most prominent
limit field's most likely transient state. The cause was a disagreement between
two files that `inverter.py`'s own docstring says to keep in step:

  validate.py `_number()`  reads "" as "use the default", so rule 9 saw 2000
                           and was content
  inverter.py line 515     did a bare `float(opts.get("max_w", 2000))`, which
                           raises ValueError on ""

So a shape rule 9 TOLERATED could not be composed at all - the docstring's rule
inverted. The roster path never had this: `_entry_max_w` already guards. Only
the flat single-inverter path did. `_flat_max_w()` now reads empty as the
default exactly as `_number()` does, and unparseable as 0.0 exactly as
`_entry_max_w` does, where rule 9 refuses it by name at line 790.

⚠️ THE FIRST ATTEMPT AT THIS MADE IT WORSE, AND THE PROBE CAUGHT IT. Guarding
`build_roster` in `selfconfig` with `except: return validate(opts), []` turned
the 500 into ZERO PROBLEMS for `max_w: ""` - the validator has nothing to say
about it, so an empty list came back and the page would have ENABLED SAVE. A
crash became a silent acceptance. The guard is kept as a backstop for shapes
neither file anticipates, but it can no longer return an empty list: if the
roster cannot be composed and the validator names no reason, that disagreement
is itself reported.

MEASURED after the fix, `problems_and_ranges` with no HA:
  max_w 5000, slew_w 400   0 problems      (the live shape)
  max_w "",   slew_w 400   1 problem       rule 10, "against a site rail of
                                           2000 W" - clearing the box FAILS
                                           CLOSED on the live install rather
                                           than silently halving the rail
  max_w "",   slew_w 0     0 problems      accepted at the 2000 default
  max_w "abc"              1 problem       "max_w 'abc' is not a number"
Before the fix, both "" and "abc" raised ValueError instead.

N2. `translations/en.yaml:7` said "all 71 keys ... so ALL SEVENTY are rendered".
The 70->71 correction had been made in one half of the sentence and not the
other. 59-of-71 required is correct and was re-measured.

Suite: 24 files, all pass.
